We ordered 2 milkshakes only. After 15 minutes we buzzed and asked how much longer. We were told "when it is your turn we will bring them". Obviously liquid drinks are put in the same category as food. Five more minutes and we left - went to McDonalds.
While we were waiting, 2 different workers came out with trays of food and couldn't find their cars - the people got tired of waiting too.
Poor service, beware!
