This is for those of you looking for gluten free food--this place was wonderful. I have extremely sensitive celiac disease and can never eat out when I'm in my hometown, as no restaurants there understand how to cook for and serve someone with celiac disease. I always get sick. While in Charlotte visiting family, we went to Burger 21 and I decided to give it a try since it had great reviews on the Find Me Gluten Free app. I'm so happy I did! They have a gluten free menu so you don't have to wonder at all what's safe. The people working there seemed very cautious with my order as well. They have a completely separate preparation area and fryer for gluten free orders. The burger I had was delicious, and so were the fries. Not a single hint of a reaction, either! My family also loved their meals. I definitely wish we had one of these in Houston.
