Review of Wahlburgers

I ordered the juicy lucy with fries. I also tried the signature sauce. The food was pretty good, but unfortunately I felt mildly glutened. I'm thinking some cross contamination somewhere. I ordered it to go from the cashier and said it had to be gluten free. She said they have dedicated fryers and a gf bun. I'm wondering if they cook only hamburger on the flat top, or do they also toast buns, etc....on there. My advice would be to ask more questions, if you are going here.
