Both the food and the wine menus are way more than just descent. You will for sure find something to satisfy your appetite, be it seafood or pasta dishes, delicious salads and desserts going all the way to stunning ribeye steaks and traditional greek dishes like mousaka. Their cocktail menu is amazing and delicious, too.
In case you just need something else than the regular tourist-trap fast food or "restaurant", you should definitely visit Paparouna. Besides the great menu, they're having a daily special, too.
They're having an every-day €10 3-course menu. There is a separate menu for that, but it's still a sweat deal.
