it's been posted here before, but it's worth repeating that lunch at Jean Georges is the biggest bargain in town. My brand new wife and I celebrated our wedding over an amazing lunch there today, with JG himself in the kitchen! Lunch price: $24 for two courses, $12 each additional course.
We opted for three courses, with a glass of wine and dessert (for a fourth course). Total bill was $190, but it can be much cheaper if you do only two courses and no wine.
As for the food, WOW! I can't believe we had four-star courses for $12 each.
If you're looking for a very special lunch and don't want to blow the wallet, keep JG in mind. it was a really special, reasonably priced experience.
