I took my brother and girlfriend here for a late lunch and was very pleasantly surprised, despite the place being packed--we were seated within minutes, despite a line of waiting patrons. I am not much of a midtown fan (with a few exceptions) when it comes to dining, but loved Avra. Think Milos or Thalassa, but with a much deeper menu. Perfect cheese & olive plate, Stuffed Grilled Octopi were fantastic, my salmon wrapped in grape leaves was new, interesting and delicious, brother's swordfish was perfectly cooked and seasoned well. Assortment of desserts (to appease my girlfriend's sweet-tooth) were all amazing. For a fraction of a second, I thought our server wasn't going to come over, but as soon as i lifted my head to look for him, he was there and remained attentive the rest of the meal. Not inexpensive, but you won't spend what you would at Milos. Avra is a very lively restaurant with amazing authentic Greek cuisine and fine service.
Pros: lively atmosphere, amazing food
Cons: couldn't find any
