Jimmy's Famous American Tavern

I was told no gluten free menu but staff was knowledgeable. This was not the case. I ended up with a pork chop and 2 cups of boiled bristle sprouts... “because they couldn’t find a clean pan” (for the sauté)... no mashed potatoes, when I asked why staff said” I don’t know, maybe they are not gluten free...” then he returned and slammed down a ton of potatoes and left... I have no idea if they are safe to eat. On vacation and at a loss for safe places to eat. So discouraged.
