I went to le Gros Jambon this past Sunday with my boyfriend. My first reaction was that that the seats overlooking the kitchen are significantly better than the seats along the right-side wall--but we weren't very lucky. ;)
We ordered two staples: fried chicken and waffles and eggs benedict with lox. They were served on these cute plates shaped like pigs. However, breakfast food is still breakfast food and, in a city that counts brunch among one of it's official meals, le Gros Jambon doesn't strike me as something special.
Don't get me wrong: it was a good meal and an interesting place, but I'd only go again if I was in the area.
