We've been there three times and loved it. Such a great atmosphere and food. If you want some authentic and non touristic place this is a right choice. Prices are good and service is friendly.
Salad and appetizer portions (grilled vegetables salad, fava spread, beets) tend to be generous servings. Recently they are skimping on the fish and seafood entrees, compared to about a year ago.
Great food and service. Traditionally Greek, very near plaka but not a tourist trap. Try the fillets, the talagani cheese, dolmadakia, meat balls, portions are generous
Not recommendable during rush hours (~2pm). The staff is totally overflowed, shouting each others and treating customers incorrectly. After 20 minutes we left the local without being attended.
