We used to visit this fish tavern very often mainly during lunch time when we lived on the south coast of Athens, due to the fact that the place is very nicely located offering sea view, cozy atmosphere and wide variety of fish snacks and dishes, being competitive when talking about price and taking into consideration that fish tavernas in that area are pretty expensive.
The service is good and fast enough, welcoming staff (kind and patient with kids).
Our favorites are fish soup, smoked eel, grilled Salmon souvlaki, shrimps with sesame, bakaliarokroketes and tomato salad with katiki and rocket.
I would evaluate appetizers and smoked&salted dishes of this restaurant - 4 out of 4.
As to the traffic - the place is very packed on Fridays late afternoon and weekends, during weekdays not that busy and more pleasant.
Would deffinately visit it again.
