Review of Fuddruckers

I was told by a manager there was a gluten free dedicated fryer. Was told to ask for no seasoning on fries and I'd be ok. They do have gluten free bun for $2. Burger was tiny. Service slow. Got two fries in and I found fried remnants of either an onion ring or chicken strips. Found another manager and showed it to her. I told her how I was told it was ok and that they used a dedicated fryer, etc. she said "we use a separate fryer but sometimes the baskets get moved around. You should have been told this is not a gluten free kitchen." I said I wasn't told that and I understand that however, I'm asking you not to say you have gluten free when clearly it's not. Her response "ma'am we are really busy". Not impressed. Won't be back.
