Barely any clients there still staff unable to keep up. Manager on duty can't even reply to a simple question of which sauce is in a certain burger. Over 90 minutes before closing they already closed of 60% of the restaurant (we and 2 other clients were still actually seated in that area eating our burgers) after finishing meal we couldn't empty our tray in the garbage cans, since they were already too full.
