Mussels were off

Firstly we wanted to order sushi, but there was no salmon. Secondly the bread was off and asked the waitress to take it away and she brought fresh bread that was apparently at the back. Thirdly we ordered with my friends 3 different platters all including mussels, and all our mussels were off, we called the waitress (Fransisca/Fransina) and asked that she call her manager (Johnathan), the manager arrived and didnt even bother to introduce himself just stood there and we had to ask who he is. We then explained the situation and he brought back 8 mussels and they were also off. We had our meal and wine and left and put the 8 off mussels on the table where the manager was sitting. What drama we got from him... Geez!! Theee worst food ever!! NEVER going back there again I'd rather have KFC.
