Review of Burger Bach

They have great burgers and gluten free buns, but on my last visit (08/27/16) I told the waitress that I had a gluten allergy and wanted a gluten free bun but I was served a burger with a regular wheat bun. I asked the server if it was gluten free, and he checked and it wasn't, so he asked if he could bring me a GF bun to put the burger on. I said that was unacceptable, so they made me a new burger, but I was still unimpressed.
