We only visited Fira for one day during our 4 nights in Santorini, but oh boy, was I pleased to find this restaurant !!!
The waiter was awesome, friendly and welcoming. We sat on the open terrace / balcony with views out over the sea, and it was in the shade which was fantastic because it was a HOT day.
The food was just wonderful. We had a selection of meze starters only - mackeral with ouzu, bean dip with homemade bread, and meatballs. The presentation was equivalent to what I would expect from a 5* London hotel, and the final bill didn't make me fall off my chair either as it was worth every euro / cent.
We asked our waiter to recommend a dry white wine, and he recommended a wine that was just spot on.
Definately seek this place out - I am just sorry that I was not able to come here for a dinner, as I think it would have been out of this world.
