A “sit down and linger” ambiance, simple but delicious food, and reasonable pricing—that’s a rare combo in Manhattan. It’s the reason this sleeper is always packed, drawing an under-40 boho crowd who lounge in a warren of artfully distressed-looking rooms (rough wood tables, mottled gray walls, beamed ceilings), chowing down on such Greek classics as grilled octopus, savory spreads with pita, and roast meats or whole fish—the latter big enough for two, slathered in a perfect lemon-olive oil sauce, and a steal at $25 (including a side). Two notes: Don’t be confused by the awning’s Chinese characters (a leftover from the previous tenant) and don’t leave if you see a line—it moves quickly.
