jean georges lunch?!
There is a prix fixe. I haven't eaten there but I just hosted an out-of-town guest who is quite the gourmand. He grew up in Manhattan and was interested in dining at spots that offered extraordinary meals, rather just okay meals. He went to Jean Georges on his first day back in the city for lunch. He raved so much that he went back again on his second day. He said it's absolutely a fantastic experience all the way around. I don't know if you need reservations, but it's probably a good idea anyway.
