They give a bad customer service and always ask for 15% tip. There was hair in our ice cream, we told the waiter ( he's one of the supervisors) he took it and brought the same ice cream scoops in a different plate . Didnt bring everything we ordered. At the end they brought the bill with 15% tip included and if you refuse to give 15% the waiter looks at you with a look as if his service deserves 15% tip. 15% is for an average service but when your service is not what we expected you don't get 15% tip.
