What you're getting: Rack of lamb
Not just a restaurant, Mythos Ouzeri is something of a supper club, with a large bar area, DJ booth, stage, and dance floor. With its large space (and ouzo by the bottle), Mythos is amazing for large groups looking to party a bit after having a great Greek dinner, which you can enjoy even on the later side of the night, as the restaurant stays open well into the evening.
What you're getting: The calamari
A meal at Marven's will get you huge portions of delicious Greek food at very affordable prices, which is hard to pass up. Renowned for its calamari (some say it's the best in the city), Marven's also makes a mean souvlaki, quail, and lamb chops, among many other dishes. Just be sure to bring cold, hard cash, as Marven's doesn't accept debit or credit cards.
