The mussels we have eaten here were the best. That particular white sauce was so delicious, I think was made with Ouzo ( an authentic Greek alcohol, kind of a liquor). The beef steak was also tasty. The place is closed to the harbour, part of the long chain of restaurants you may find next to the sea. The service was good, good value for money. Give it a try if you end up in Rethymnon.
