    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!! everything is clearly marked on the menu. your burger choices are a little limited, but totally worth the dedicated kitchen space and how careful they are with my food. my tray even had a bright green gluten free sticker on it. I will be back!

    I was really looking forward to eating here after all the good reviews however my experience was not as positive. I ordered a GF burger along with GF fries. My husband ordered a gluten item. My burger was in it's own bag marked gluten free but the gluten free fries were in the bag with my husband's gluten meal. This makes no sense at all :-( Definitely not safe for Celiac.

    Manager stepped out to give us the GF run down of their kitchen before we ordered. Here is how good it was: the fries came out later than the burger, and the manager came out to explain that kitchen staff inadvertently set the fries down in a non-gf area: they had to start over to make sure I had GF fries!! Thanks Burger21

    Burgers are pretty good. Nice to find a place that has GF sweet potato fries, that is rare. I only wished their fries were more substantial, they are super skinny shoestring fries. If you order burger without bun pay attention to what they charge, they tried to charge us extra for GF bun even though we didn't ask for them.

    Okay I have not eaten here yet, but it sounds great. I called to clarify some things: Are the shakes gf? The answer I was given was YES, they can be made gf. Might want to ask more questions, but it sounds good. Secondly, it lists gf beer, but they mean cider - Angry Orchard. I wish they would carry my favorite beer - Red Bridge. The ciders don't really go with food.

    Gluten free buns, menu and a dedicated fryer. Staff all seemed well trained and made us feel comfortable from the start. They also have a separate grill space for GF orders. Liked having a few dipping sauce options clearly labeled as GF. I'm not sure if it was the manager or owner operator, but he went out of his way to make us feel comfortable and checked on us during our meal as well. Great experience overall and the food was tasty.

    I'm really glad these guys opened here. They are new so be really careful, they swapped my burger and my husbands so my supposedly GF burger came out with not GF grilled onions. Luckily his had cheese too so it was easy to identify the problem and they made new ones that were hot and delish. My favorite thing about this place is the GF sweet potato shoe string fries. They are perfect every time. Hubby loves their shakes. The GF buns are pretty good but they also offer lettuce wrapped. So despite the goof, I would come back. I feel that they are designed to be celiac friendly, but again, new place, new staff, be your own best advocate.

    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.

    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.

    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 amazing shoestring fries - my favorite variety - were absolutely delicious. I was so excited to be able to eat some yummy fries without having to worry about getting sick later on from any cross contamination! Lots of beverage choices, had a cold glass of iced tea, but really want to try a shake next time.

    Edit: Sadly my son was glutened the last time we ate here :( It was one of the worst experiences and took him many days to recover. I don't know what went wrong, only clue was they said the bun tasted like the real thing. I wonder if our gluten free request was not relayed to the cook. It was a busy weekend....Previous review: Celiac child had no issues whatsoever! The persons who take the order are knowledgeable about celiacs and the servers too! And the burgers are delicious, so are the sweet potato fries! If you have to drive a long ways to get here, assure you that it will be worth it!

    They have a dedicated fryer and space for gluten-free. Their food is delish. I will say that we have eaten there several times and on one occasion it seemed that it was taking a long time for our food to come out. That us when the manager came out and told us that there was a mishap with my meal (rest of family is not gluten-free) - he said that my burger received a regular bun and that they had to remake my burger. The honesty in the management team that was awesome - they could of just change the buns and I would of not been the wiser until later. And later I would have been in the hospital because I am pretty sensitive. B-21 from that day has my loyalty but I also tell them when making my food - it is not a diet for me but a true health situation. So I have not had any problems and we were told that one of the owners daughter's had celiac --- that was why the chain is so celiac friendly!
