We went to Santorini in August 2007 and tried a few different restaurants...
To be honest, I kept wondering if there are any "bad restaurants" on the island... Greek food is always great in Santorini, no matter where you go!
The problem with some restaurants in Santorini is that if you want to eat somewhere with the view to the Caldera and the Sunset, then you are paying a LOT of money for it... If money is not an issue, I am sure you can pick "fancier" restaurants in Fira, Santorini.
Ampelos is a restaurant where you can get the amazing view, has a nice atmosphere, the food is great, and has a fairly decent price for all that!
The food was the perfect mix between the greek original cuisine and but with a little gourmet touch! The portion was great and we enjoyed our dinner at Ampelos very much!
