When I made reservation I was told we can stay maximum 2 hours. I said ok. When we went there we were almost finish our lunch and I was still drinking my pint after 50 mins. Then waitress brought the bill without asking. Then she came back in 5 mins to get the bill. I told her we are not ready to leave we have 2 hours. Then she gave me weird look and left. I felt terrible for taking my friends there. Whereas, I read good review and had high expectations.
