Great place drink are bit expensive 15dollars for a non alcoholic drink is way too much and my waiter clocked out so the new waiter didn't do anything we didn't order anything after that and when we were about to leave he was asking for more tips, that is inappropriate to ask for more tip, ask your boss for a raise not costumer for a tip as it is costumer choice to give whatever feels is right depending on service and my tip was good not a low number
