The service is poor, the menu says there is a "banana split" drink so we ordered it, the waiter comes with a banana waffle. We explained to him that we had ordered a banana split drink. Then he remembered to tell us: "There is not this drink." We asked for a cookie. After fifteen minutes, we did not get anything. Apparently the waiter did not even write it. We left disappointed. We received a gift of condolence: a few miserable chocolate cubes and a response, "Yes, we know our service is bad."
