Counterstaff (very rudely) informed me that none of the burgers are gluten free, even without the bun. I'm not sure how well informed they were, but their disdain and unwillingness to try very hard to find out the ingredients made me feel unwelcome and unlikely to eat there.
I asked if the fries were done in a separate fryer and was assured that they were. I actually leaned over and asked the guys cooking them. :o) I did not get sick. The fries are all on the well done side but they were still pretty great for those of us who don't get them very often.
UPDATE 12/27/2016: I learned today that they no longer have dedicated fryers - all of the oil gets filtered and mixed together every 15 minutes, so even if they are frying items in separate fryers, the fries are getting contaminated. The person I spoke to described it more as "gluten friendly". ----- Original review from April 2015: This is one of the first places I ate at after being diagnosed with celiac and it continues to be one of the best. There are no gluten-free buns, but their burgers are amazing without the buns. (Sometimes I will bring my own bun.) The managers are very knowledgeable about cross contamination and making food that is safe for all to eat, including celiacs.
They don't have GF buns, but we brought our own. The fries are amazing. My boys are not Celiac, so we didn't have any issues (as some noted on other reviews). It was too busy to ask if they had a dedicated fryer, but their menu doesn't have many things that seem to contain gluten that are fried. My youngest said: "a five star for sure." I like to reserve 5 stars for restaurants who have GF bread, buns, etc, but they loved this restaurant and no one got sick! Recommendation: call ahead at a slower time and ask about dedicated fryer.
I've eaten there twice for a milkshake and fries. One time I ended up throwing up. I was hoping it was unrelated, and when in for a burger, and noticed that even though there was a separate cook top for burgers... The cook was pressing the spatula onto the bun as he transferred the burgers.
