I've heard less than positive things about Nomi. Aside from the high prices (which you can pretty much count on going in), the attitude of the staff there is supposed to be less than stellar. I've also heard that the setting (i.e., the seats in the window area overlooking the Watertower) are usually impossible to get and are often left open in case VIPs show up.

Avenues--across the street at the Peninsula--has pretty much the same view (maybe not quite as spectacular but pretty darn good) and the food is phenomenal.
