Burger 21

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.

Amazing burgers! The GF bun is really good!

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.

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.

I eat every week and have never gotten sick. Excellent burgers and fries.

Menu clearly marked for gluten free, and care taken by the knowledgeable staff. Really great, toasted, gf bun with a delicious burger. GF regular and sweet potato fries.

Delicious burgers, very aware staff. Everything clearly marked GF. Fantastic!

I was very impressed with Burger 21. They brought my food out first and it was labeled GF. When the server brought out everyone else's food, she was careful not to reach across me to hand my daughter her gluten filled food. She instead handed it to my husband, who was sitting across from me, to pass to my daughter. I also had a milkshake because they had separate equipment that was clearly labeled GF to make my shake. They were very thorough and seemed to have a really good understanding about how to take seriously someone who is GF.

Wonderful food selection, and the staff is very knowledgeable about the Gluten Free options available. I was able to have fries and sweet potato fries, which I haven't had for years! And the buns on the burgers were superb. I definitely recommend this restaurant for anyone with Celiac!

GF buns are fantastic. They asked if it was an allergy and all food was delivered separately and labeled GF. Highly recommended.

They have a gluten free menu and dedicated dryers for sweet potato fries and regular fries. Gluten free chicken tenders on request.

I asked for a gluten free burger. She said, "we don't have gluten free burgers, only gluten free buns." I tried to ask her why, was it cross contamination, or what? It is on their menu. Why would you have a gluten free bun with nothing to put on it? She just kept barking, "we don't have gluten free burgers, only gluten free buns!" So I walked away.

Very good place to eat. Menu is very clear what is safe or not. Fries have a dedicated fryer and are SAFE and delicious!

Excellent! Menu very clearly marked with GF options. They have a separate are to prepare and cook GF food. Their GF buns actually held together when eating them! Delicious burgers and fries! They have GF regular and sweet potato fries!

Had a gluten free bun as promised. Indicated fries weren’t safe so I skipped them. Always appreciate advice from the employees on site. After they took my order they went in back and called out that it needed to be gluten free with a gluten free bun.

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

Separate fryer... GF buns and options! Great place to eat. Never have had a problem!

I have eaten here many times, they always ask if the gluten free is for “allergy” reasons and make sure they are very careful. Really good burgers and sauces

Awesome French fries! Confident staff, separate prep area for gf.

Updating my review bc service is much better lately. We order from here at least once a month. Kids love their burgers with GF buns, delicious fries and yummy milkshakes. 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.

Rather large GF Menu. Menu online. Celiac son...no reaction. Good Burger & Fries. Highly recommend if you’re in the area.

Great experience. Food was good and lots of GF options.

Staff were incredibly knowledgeable, friendly and amazing. Cooked all GF stuff in a separate area. One of the best burgers I’ve had in a long time. Sweet potato fries and strawberry milkshake were so good too!

Dedicated fryer for fries, great GF buns and burgers - items were tested on my Nima Sensor and came back with no gluten found. Menu is clearly marked and noted when order is placed.

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.

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

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!!

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.

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.

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

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.

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.

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.

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! 💚✅
