Burger 21

Dedicated fryer!!!! And separate utensils!!!

My son has a severe wheat allergy and has eaten safely here twice. Dedicated fryer. The gf buns were delicious! Gf french fries are excellent.

They seem to be very careful and cautious about the food. I recommend this place.

We used to go regularly but service has gone downhill in the past 12-18 months. No issues with the GF food and they do well labeling and making fresh fries.

My wife and I visited this weekend. She has gluten intolerance, not diagnosed with celiac. She ordered the mushroom burger, specifically labeled GF, and specifically asked for a gluten free bun. She woke up this morning with definite symptoms of eating gluten - very severe reaction.

they did great!!! I have not had a milkshake out at a restaurant in years!!! The french fries were yummy, and I had a gluten free hot dog on a gluten free hamburger bun (they did not have GF hot dog buns) all and all a great visit and I will be back!!!

Separate grill, fryer and milk shake maker. A separate server for all GF items. The buns are amazing. Def our favorite burger joint!

Excellent burgers and fries prepared separately. Very aware of GF and warn you about everything, even the shakes.

Unfortunately, for me I got glutened after eating one of their burgers.

GREAT GF menu! The hamburgers are awesome, and they have a dedicated fryer. GF sauces are marked, and they even have a GF kid's menu. Our new favorite family meal out!

Very very safe!! Cooked in a separate area. Even better - its delicious!!!

Burger and fries were good. Didn't like that the bun immediately crumbled.

Good good and great GF practices to keep celiacs safe!

08/2014 - This is a great new option for quick food in the area. 07/2015 - Update: from 5 stars to 3 I've been coming here for a year now. I've never gotten sick here. That said, they must have changed their burger recipe fairly recently -- they are INCREDIBLY salty to the point where we've stopped frequenting it.

delicious

You can have milk shakes and burger and fries all safe for Celiac's!.

The GF milk shakes are wonderful!! The buns are lighter than I've come to expect with GF buns and crumble, and today the toppings were surprisingly sparse. Still, it was another good meal

Separate fryer and hyper-awareness about celiac. Food is great. The GF hamburger bun isn't terrible either.

This was a great experience for the entire family. Delicious juicy burgers on GF bread with awesome shoe string fries. All of our baskets of food were identified with GF stickers. Highly recommend this place.

The hamburguers taste really good with the gluten free bun and they fry the French fries and sweet potato fries separate to avoid cross contamination. I trust this place. Never been sick afterwards.

We like this location a little more than the Ashburn one. They have more comfortable seating, a Coke Freestyle machine, and a pay car charging station. Usually it is not as crowded as Ashburn. Daughter likes the GF burger and GF fries, and has never gotten sick after eating here.

Burgers were delicious! Gf fries and shakes!

Staff knowledgeable and food was marked as gluten free and server said it was upon serving it. Great burgers and dedicated fryer.

Staff was very helpful and allergy aware. Feel very safe eating here. We will be back!

Celiac friendly. They have a dedicated kitchen section and take necessary precautions. Burgers were great and tasty, i liked that they had multiple types of sauces, each marked if they were GF or not. Great family destination. I would recommend the restaurant to put a bit less salt of their fries.

My son and my wife loved the burger and felt really safe. We found the restaurant via Find ne gluten free apps and nice discovery. The food is not only safe but really delicious! The concept is great for great food fast!

This store is no longer open. Go somewhere else

They were amazing, helpful and careful!

Staff was extremely knowledgeable about gluten free and what constitutes gluten free. I asked if the fries were fried in their own fryer and the server seemed surprised I would even ask. Was told “well they aren’t gluten free if they aren’t in their own fryer”. Yes!! They have a dedicated fryer for all gluten free orders. Order came out with a sticker indicating it to be gluten free. Bun was great! It didn’t fall apart at all. Will definitely be going back!!

Their menu and sauce dispensers are labeled for GF items & their fries are in a dedicated fryer. I ordered the ‘shroom burger which was delicious. They brought it out separate and the basket it was in was labeled GF. The GF bun was fantastic and held together completely. They also have GF milkshake options.

Absolutely delicious!!!! Great gf buns and even better they have gf fryers for fries!! I will travel an hour for a good burger and fries, they’re hard to find.

I’ve eaten here many times with no issues. Burgers are delicious and you can never go wrong with gf fries. I always let them know I have a “gluten allergy” and order a gf bun and gf fries. Amazing!!!

I tried the cheesy burger. It was yummy and had no reaction after eating it.

Best gluten free buns around, fries prepared separately so no cross contamination 🎉👍

Have safely eaten here on several occasions. Had one mixup on a carryout order that got us sick (they put wrong bun in the GF order), but will stick to eating in the restaurant from now on. Love the GF sauces, which are clearly marked, and the gf shakes are great! Kids love this place. Very understanding staff.

Had the new Impossible Burger that was GF on a GF bun and fries cooked separate. Just mention to the staff during your order you'd like it GF and they will take care of it for you. Now need to go back and try the real Burger! Great place.

Great every time! Great GF buns and they have the best fries! Labels all their sauces so you know what is GF. Eaten here many times and never had any issues or concerns.

Amazing burgers! The GF bun is really good!

They served me a regular bun and I didnt notice until I had already taken a bite. Use extra caution if youre going to use them before your flight

Burger was delicious and did not get sick. I’m a fairly sensitive celiac. Slightly cheaper than grassburger.

So tasty, so safe - a real treat. Their GF safety process seems to be spot on. The GF condiments and menu items clearly labelled too (see photos) and its a pleasure to have GF Fries and a choice of tasty burgers including some of their signature flavours rather than being stuck with a plain cheeseburger. The milkshakes are a dessert in themselves and are a welcome safe treat 🎉 Service great and toilets and restaurant spotless too.

Needed lunch to go at the airport. Gluten free bun, no fries. Staff wasn’t knowledgeable but they were cautious first saying that all they have gluten free is the bun. Questioned about the burger and they said oh right, yep that’s all beef. I double checked that nothing is cooked on the same grill top as the burger. They were very nice and accommodating- I ordered before they actually started serving lunch but I needed something for my long flight home and GF reviews of their area restaurant chain are very good.

Nice gluten free menu. I feel safe eating here.

My daughter was so excited that she could simply go to lunch and eat a burger and fries. She also enjoyed a chocolate shake. Awesome experience for a seven year old six months into her celiac journey.

They wanted to take the goat cheese out of he salad since they weren’t sure if it had a gluten contamination. The cheese is what makes the salad!!!!! I walked out in frustration and ate next door at Tijuana Flats.

Gluten-free bums but they have a shared fryer so the fries aren’t safe

Staff was friendly and understanding. Celiac’s food was prepared and delivered separately. Food was yummy. They forgot the grilled chicken in my salad, but o chose to let that go and lower my calories with this lunch.

This restaurant was wonderful! My daughter, who has Celiac, was so excited to get a cheeseburger and French fries. All of our food was delicious. She did not get sick from eating here, and she’s sensitive. Wish we had one closer to where we live!

This place has such fresh ingredients. We won’t eat Red Robin or grassburger anymore. They cook it to perfection. They have a dedicated fryer for fries. They have a special place to make ur gf burgers just ask. They gave gf buns and lettuce wraps. Everything is clearly marked and the staff is so friendly they’ll help u make modifications. They also do sweet potato fries and the self serve sauce bar as 7 different condiments all clearly marked as to what’s gf or not. I’ve never gotten sick here. And the ingredients r always fresh and burger is juicy and fresh.

They had a great gluten free selection including all sauces available being labeled for gluten content! Only complaint is when we first got there they were out of gluten free buns so I had to wait for a worker to return from “picking some up” whatever that means.

One of my favorites! They have really good gluten free buns and the fries are gluten free as well. This is one of my go-to places and I have never been sick. They even bring out the gf burger in a separate basket with a green dot sticker labeling it gf.

Delicious, safe food! Love that they have safe fries too!

Great place to eat. And they have cans of cider

The staff was knowledgeable. Excellent food w a lot of selection. Legal fries! Everything clearly marked. We will b back!

We eat here regularly. My husband who is not GF loves this place too! They take great care to serve safe food. It’s great to have a bun, French fries and milkshake like a “normal” meal, not a bun that falls apart as soon as you bite into it as is the case with a lot of GF buns. Their salads look great but I always get burger & fries because they are the best around, not just for GF but everybody loves them!

The turkey burgers are NOT gluten free. Everything else was okay, but I ended up stuck with just fries. The chicken my daughter had was very bland. Not going back.

Wonderful GF options! The food was great and they were very knowledgeable about preventing cross contamination. Our GF food even came bagged differently. They have GF buns and fries! We will be back!

I’m celiac and I would recommend this place! It was delicious! I had the cheesy burger and sweet potato fries. ALL GF! The staff was very friendly, and reassured me that all GF food were cooked separately on different grills and separate fries. I waited 5hrs to leave this review to see if I’d have any reaction. And NOTHING! 💚✅

GF items are clearly marked and prepped in a separate area. Sweet potato fries were great, plus several GF dipping sauces were available. Also have GF shakes! Have eaten here several times without issues.

Super disappointed to find out they’ve switched from having a dedicated kitchen space to “gluten friendly.” Their menu now claims they can’t promise gluten exposure.

Great restaurant for a Celiac-friendly gluten free burger and fries! A cute atmosphere added to the pleasure of our dinner! Staff was knowledgeable, menu is clearly labeled, condiments (which you pour yourself) are labeled! There’s even a sink near the entrance just to wash your hands when you arrive!

So yummy. Burger 21 is a trusted gluten free spot. They are excellent with cross contamination and ensure celiac food is prepared properly. I was told they wont even carry out gluten / gluten free together to ensure no mistakes are made. Great staff too at this location.

Manager has a family member with Celiac so they get it right. Burgers are delicious, to my knowledge there is a dedicated fryer for the GF fries. Shakes are amazing and there are GF sauces and dressings! My favorite place to eat.

Loved this place. Staff was helpful and knowledgeable and the menu had the many GF items clearly labeled. Our celiac daughter loved her burger. My mother is not celiac but avoids gluten, and she ordered the shrimp burger on a GF bun. The staff immediately notified her that the shrimp burger isn't GF, so good on them.

Amazing burgers!! All 5 celiacs in our family ate salads and burgers and no one had a problem. Great place to eat! Wishing we had one back in Kentucky!!

Great place! Celiac safe. Even had shake. Awesome!! We will be back.

Staff was very nice. Burger was excellent! They have a separate fryer for the fries.

My go to place for lunch. They take great care in their gf food prep and I've never gotten sick. Plus its delicious!

I was thankful to find this Burger 21! The staff is very knowledgeable and they have separate prep areas and fryers!!! We are celiac and My kids were overjoyed to find a Burger 21 that can meet our allergy needs!
