My wife and I arrived around 6:45 and were seated without a reservation - but from what we could see, we got very lucky. The waitress was extremely helpful as my wife is allergic to gluten. She asked what dishes we were interested in and then checked with the chef. We ended up ordering the Anogi Salad, Grilled Octopus, Meatballs, Lamb Shank, and some wine.
Everything was a delight. The salad had crisp lettuce, a delightful dressing, and plenty of character. The octopus was tender and tasty. The lamb was absolutely packed with flavour. The meatballs were also very flavoursome. The wine was good too, and kept cool in a little ceramic carafe.
At the end of the meal, we were given a dessert gratis. 60 euros total for wine and 4 dishes, as well as some water.
The setting - no sea view here, but inside/outside seating next to a small square in the centre of Imerovigli. No distractions from the food :)
We'll be back.
