Top notch, we found Phaedra on our 4th night in Kefalonia and spent the majority of our last week there. The kalamari were the best I've ever tasted and my fiance had them everytime as a starter. The King Prawns Phaedra were also superb as was the Spetzofai. Service was excellent with nothing being too much trouble.
Very poor meal, the moussaka was appalling and they couldn't even get the greek salad right. Waiters were obnoxious. Don't believe the hype it is very over rated.
Our second favourite restaurant in Lassi. The king prawns were superb, but the coup de grace was the red snapper fillet - very tasty. Very clean place and a nice atmosphere.
