Check the prices before ordering and VERY CAREFULLY. Fish is served with a "price per kilo", but there is no way to check whether the exact weight is in the bill and in no way to choose the weight BEFORE ordering.
How it should be: the fish is weighed and the price is reported BEFORE cooking.
As it is: you will find out the cost of the fish only AFTER cooking and the actual weight of it will be 2-3 times less than what will be included in the bill.
I highly recommend not to visit.
