If you are looking for a truly magnificent greek restaurant that is it.
Location: A bit outside but not too far away from the city center. Parking spaces are rare in the area and since the restaurant is almost always full (reservations highly recommended) you may need to search a little bit. But due to the free bottle of Ouzo per table, a taxi drive might be in order.
Staff: Friendly, helpful and trained in a very good way. One can feel it is family driven and even small hiccups will in almost all cases be righted by the staff under the good supervision. One can feel that they like there job. Low turnover.
Food: Absolutely great. You will not get the heaps of meat you get in a lot of greek restaurant but instead with the order of an entree (main) you will get greek salad, baked potatoes with cheese, and two or three (changing) other appetizers (at no additional cost). There are very good meat and fish options with pretty nice sauces (try the raisin sauce or the trio of filets) and all is freshly and well prepared (beef and lamb to your liking) and tastes really great. The meat is of very high quality.
They do have a nice winelist on the menu (not Retsina very good greek wines, I was pretty surprised the first time I was there) and a bigger one with more expensive choices, no actual need to go for those).
Ambience: A very nice and unobtrusive decor much like an upscale restaurant, not the classic blue and white of many greek restaurants.
As you can see, I am 100% convinced by this restaurant, we go there on a regular basis (once or twice a year) and it has never disappointed. It is of course in the upper scale of the prices as well, think 25 € for a main, but excellent value for money considering taste, quality and the appetizers. Oh, by the way, try the desserts.
