To be honest, I tend to over-scrutinize when it comes to decisions on where to eat, what to do etc... while on vacation. But based on reviews and even recommendations from the hotel staff, our party of four (husband,myself and 18 and 19 year old girls) decided to eat at 1800 while in Oia. And while we knew it would be expensive, we were unprepared for the VERY tiny portions that are served. We are not voracious eaters and have dined all over the world, plus we definitely don't mind handing over a large amount of euros when we leave the table satisfied. The presentations were beautiful, the establishment is lovely.....just be prepared and not too hungry!
