No sushi on sushi special night?!

Just waited over an hour for sushi order on sushi special night. To such an extent that order was cancelled to go home by 20:30. Arrived at restaurant at 18:50. Our waitress was a star and even more frustrated than us and the 5 other tables complaining and waiting for sushi. When I got up from our table to cancel my order the was one cleaning lady behind the sushi bar and no plates on the belt. When we left some of the staff had returned but there was also a waitress trying to make sushi for her table that had been waiting over an hour for their sushi order. Really dissapointed and still hungry!
