Imerovigli is the little town at the highest point on Santorini. As evening approached, we didn't want to stray far from our balcony at Langas Villas, which offered sunset views that dreams are made of. Luckily, this restaurant was right across the street. Also luckily, we went early, which meant they had room for us. Turns out people come from a lot farther away than across the street to eat at Avocado. The servers were friendly and warm. The complimentary glass of ouzo and amuse bouche of cheese was welcome. The Greek salad of local tomatoes and perfect onions was packed with flavor. The risotto was delicious. But it was the fried potatoes, sprinkled with local cheese and smoked salt, that made us make a reservation to ensure that we would dine there again before we left Santorini.
