Burgeezy serves vegan substitutes such as the beyond and impossible burger. They also serve the vegan chicken sandwiches (but those are not GF). Their burgers and fries are GF and come with a GF bun when requested and the fries have their own fryer! The only burger ingredient that is not GF (to my knowledge) is the bacon. The first time I ordered from them the owner called to reassure me that everything is cleaned and cooked separately!
