Coming in from LA, during NY restaurant week...
New York chows:
we'll be in the city during NY restaurant week. Are these really good deals?
Is lunch better than dinner?
Any particular restaurants better than others?
We're looking at maybe lunch at Union Square Cafe if we can get in, and also maybe Bolo?
11 Madison Park?
The advantage of both USC and EMP is that they are both Danny Meyer-owned, and he's reliably generous in his offerings during Restaurant Week. You will not be treated as a second-class citizen during RW; in fact, the last time I went to EMP at RW, I believe we were not even offered the regular menu.
Looks like you are not very familiar with NYC and relying on an old Zagat's. If you are in town for only a few days I would just go to places that interest you (with good kitchens today) and not worry about restaurant week.
Seeing how most of these replies have yet to suggest any other RW choices, here are some of my favorites in order from best to semi-best (I've been to all of these places during RW):
Aquavit (Dining Room)
Craft (this may not be on the list this time)
