Just returned from fantastic 2 weeks staying at Efrosini. Went on 3 occasions throughout the holiday. First time okay, nothing special but then downhill after that. Lamb Kleftico definitely to be avoided, the worst I have had across all the greek islands.
To be highly recommended. Nice setting and great food. Went to a number of different taverna / restaurants throughout our recent 2 week stay and Persas served by far the best greek food.
