The first time we went there was not very good because the was a blackout and the restaurant was fuller than full. We sat next to the open window where all the traffic back from Oia was passing by and we had to wait for our food for a long time.
The second and third time we went there, it wasn't nearly as full. We had tables inside the restaurant and the service was very friendly. The food was sooo good, especially the special Simos appetizer and the tsatsiki. When we asked for the recipes the chef came and wrote it down for us. The prize was much cheaper than the restaurants with caldera view.
