They have gf buns and their patties are all meat/gf. They share a cooktop with the regular buns, but I asked if they could wipe down and they did. Everyone was really nice. All of their sauces and other ingredients are (according to them) gf. These are some of the best tasting burgers in town (tried before diagnosis), but it may be risky for some who are very sensitive to cross contamination. I did not get glutened at all and it was a great experience.
