Only about 20 items in the menu.
It was located in the touristic Plaka district.
We loved this family run restaurant food, though the staff, looked like gloomy (not happy).

The Rustic Restaurant: Ampelostrates

http://ampelostrates.gr/

We wanted to go Alitzeroi, restaurant in the middle of nowhere in Lonely Planet, but it was closed. When we asked the shop opposite the Alitzeroi, she recommended us to go to this rustic restaurant in a vineyard.

We followed the direction in Google Map and finally found it this place, with bad access.
From the main road (small village asphalt road), we entered to a sand (non-asphalt) road, for about 500 metres, finally we found the restaurant.

We were happy with this unique experience.
They were open only during weekend and it was full with local people.
Their menu was hand writing on a paper and the restaurant staff didn't speak well English.
The taste of the food was OK.
In the end, the owner gave us free rakija (traditional fruit liquor).
