For the splendid view it provides of the Acropolis, this restaurant is already a winner. Even better is that the food, made using local seasonal ingredients, is excellent and very reasonably priced, given its location. And you don't need to pay to go into the museum to eat here: ask at the ticket desk for a free admission ticket.
Breakfast dishes are served up until noon, then a lunch menu continues until the end of the day. On Friday night, the only day the restaurant stays open longer than the museum, there is a special dinner menu from 8pm.
