I've eaten here 3 times and never gotten sick! The only thing with gluten on their menu are regular buns for their sandwiches (chicken, burger, salmon). Everything cooked or fried is gluten free since all items touching cooking surfaces are gluten free! They also have Udi's buns for gf sandwiches.
Food is great, safety is great, and I highly recommend the spicy fries! Owner was in there last time I went and she said lots of their family members have celiac so they wanted to create a celiac friendly restaurant with a fast food style menu. Amazing find for northern Virginia.
**Edited to add a photo of the food and the note I was given one time when I picked up my food. They are top-tier for those with celiac and other gluten sensitivities. I moved to Baltimore but every time I'm in the area, I go out of my way to grab some chicken tenders here!
