Review of BJ's Brewhouse

today I went & ordered something off of the GF menu. The waiter returned & said he questioned if it was GF so he asked the manager & they didn't think it was GF.... Why was it on the menu? i believe they were just uneducated. I appreciate that the waiter was concerned, but thought it was inappropriate that. the manager didn't come speak with (they were not busy). We walked out.
