Thalassa

If you're in New York and want some good Greek food, you basically have two options: a.) head to Astoria, Queens where there is a vibrant Greek community and lots of tasty, cheap restaurants, or b.) stay in Manhattan and eat at Thalassa. Thalassa is located in Tribeca and is by far the best Greek restaurant in Manhattan. They serve all the classics but they also have a selection of freshly-caught fish which you can choose from and then choose how you'd like it prepared. The wine list is also remarkable and they sometimes offer free tastings at the end of the meal.
