The previous review was definitely wrong. They do have GF buns. You can order at the kiosk and remove the regular but and add a GF bun. It tasted like a bun out of a package, not warmed or toasted (which is good). It didn’t taste particularly good, nor did the burger, but I took a chance because I was exhausted and didn’t feel like walking anymore (I tried walking to one other place but it was closed on Mondays).
