Worst service

I am lodging a complaint against Ocean Basket in Melrose Arch after repeatedly being provided with the worst service and attitude by the employees. The first time I found a flie in my prawns only to be told its not their fault. The next time it took the waiters 20 minutes to serve me, then today we had to wait 15 minutes to be attended to with 7 waiters loitering around there was still no one to serve us. Then we ask for the manager only to be shown their fellow waiter as the manager. Their attitudes have been the worst ever and you have to ask for service for you to be served.
