If you filled a stone-lined castle with all-white furniture and some good Greek food, it’d be doing a pretty solid impersonation of Korali Estiatorio on the Upper East Side. There are plenty of big tables (including one with a full tree in the middle of it), plus a bar, and the menu has all kinds of spreads and mezes to share, plus more Greek classics like lamb kebabs and saganaki. Use this place the next time you’re looking for a relatively upscale dinner near the 92nd Street Y, or an UES spot for lunch with your family.
