Yassas, the price level in Plakias has risen dramatically this year. You pay ?2-?3 more for a meal than last year. The prices are outrageous...
Water is still free as a welcome drink - with a few exceptions. Olive oil is nowhere to be found on the tables.
I've just spent a week in Paleochora and the price level there is much cheaper (tavernas, bakeries, supermarkets).
Best regards from Souda/Plakias, kv
