You wouldn't expect the prices, service and food to be as wonderful as they are at this location - over looking the harbour, with the market behind you and the water and fishing fleet in front. The moussaka is the best I have ever tasted, they are lovely with the children (but aren't all the Greeks?) and beer is ICE COLD.
Avithos and Aghios Helis are brilliant - you'll be exhausted getting there, but then you can just crash before you have to try and get home again. Take your own lunch and drinks though, as the beach hut is not cheap if there are more than 2 of you! My kids LOVED Ammes beach; for them, the jets coming in to land so close were a bonus (maybe four in a day)and after 16:00 there is virtually no international traffic anyway. It also has the wonderfull asset of being only about 20 metres down from the road - and you will only know what a blessing that is when you have visited the other beaches in the area.
