Gavroche is one of my favorite restaurants in New York. I love it. I've always enjoyed everything I've had. The wine list is great. I enjoy both the bar (for drinks and food) and the more formal dining room experience.
I have several friends who like to knock it. They don't seem to like any place that is too critically acclaimed, thinking that they are being part of a heard or some such. If you know those same people, don't listen. You won't regret it.
Pros: wine list,food,service
Cons: none
