I called ahead since I have multiple food allergies. I was told that there's options for me and that the waitress would talk to the chef. After arriving, the waitress handed me the menu showing me the marker for gluten free and said she wasn't familiar with soy so she would let me figure out what I can have. Their idea of a gluten free burger is a $10 patty. We left without purchasing anything
