I was treated like a thief after spending almost $200. When leaving the restaurant one of the staff thought we didn't pay our bill and started to say that she was going to call the police on us. The way she approached us was very insulting and rude, she didn't ask us a question or even to see our bill. The worst part is that both of my daughters were there and after we left the 5 year old was scared that the police was going to take us and we had to explain to her that we didn't do anything wrong. I tried to talk to the manager but it looked like the manger was new and did nothing about it. We walked away with no formal apology.
