A very high-quality supermarket (in my opinion better than the nearby Carrefour), visited in the summer of 2016, good choice, low prices for Greece, price-quality compliance, friendly staff. Without knowledge of languages, I made purchases without problems.
Nice little supermarket. If you want to take a good cheese or olives, it is better to take them by weight, they will give you a try, if in doubt, they can recommend something.
