Wait a hour for food

Worst experience of my life at this restaurant. Waited nearly half an hour for our drinks then waited another hour for the food, very time we asked how long we still have to wait we are told 10 more min. The table behind us came there after as but received their food before us and it wasn't even busy? Went to speak to the manager and he wasn't helpful AT ALL! We then settled our bill and paid for the drinks (highly over priced) to leave and the manger asked us never to return again! Wait a hour for food and then get treated like that!!!???
