Fatburger & Buffalo's Express

I have a wheat allergy + am vegetarian so I got the Impossible burger on the gluten free bun. It was sooooo delicious and affordable! Only like a 1.79 upcharge for the gf bun which is definitely cheaper than most places. The staff was super kind too, I got helped by Luis (according to my receipt so I think it's him!) and he was great! I was having a bad day and this improved it for sure

Came in requested gluten free bun for 3 burgers. They did not follow instructions and still put it on regular bun. I have celiac and I don't feed it to my nieces because of how severe it is with me ordered 3 burgers and the manager Luis picks up with a heavy accent get rude refuses to give the corporate number and then hangs up because I was having a hard time understanding him. He kept cutting me off and over speaking me instead of fixing the issue he chose to not even acknowledge the mistake.
