Fava is a nice plate, with beans actually, onion and olive oil. Olive oil is the most luxurious oil you can taste and it is everywhere. You can buy also olive oil as a souvenir or a gift.
Choriatiki or Greek salad is the mainstream salad, with tomato (the first tomato in Greece was planted in Plaka), cucumber, feta cheese, olive oil and onion in its basic form.
Greeks consume a lot of olive oil and meat. So a local mprizola, made from pig is one dish you can definitely enjoy with your Greek salad and tzatziki.
Mousaka. Well, it is difficult to find real mousaka or mouzaka, meaning made in the restaurant where you sit. Most of the times it is pre-prepared by a catering service. This does not mean that it is of bad quality of course, but you can ask the waiter.
Pastitsio. A famous dish you have to try, as with mousaka.
Fish dishes. There are dozens of fishes you can enjoy, you just have to ask if there is fresh or frozen. Normally people are honest on food. It’s better to try fish in some Saronikos‘ islands restaurants.
