Sfoglia or Allen & Delancey
I have only been to A & D. The atmosphere is IMO a little odd, a little loud, and the chairs a little uncomfortable. But the food is so good I will go back if I can ever get a reservation again. I have heard good things about Sfoglia. I think the food and ambience of these 2 are so different from one another that it is impossible to make a comparison. I would take a look at the menus and see which one appeals to you more, but you will probably have a great meal at either. If you can't get a res at A & D, you might want to consider Bar Blanc. It's also new and trendy, with creative food, but a little easier to reserve.
only been to allen and delancey but aside from some minor service issues, this is a great place with nice front room staff, nice decor, and excellent food that i feel i cant get anywhere else in nyc.
the raviolo, the terrine are both excellent starters...the cabbage beef and onion is one of the best entrees ive had in some time.
