Would greatly appreciate suggestions for a nice Japanese restaurant that will accomodate a group (~10 people) for lunch, some of whom will exclusively eat sushi and some who won't (i.e. need place that will cater to serious sushi eaters and be willing to accomodate those who will order tempura or other "safe" items). Probably can't justify a stratospherically pricey place, but moderate/expensive is OK.
Must take reservations and be willing to seat the group at one large table and be quiet enough for us to have a nice lunch conversation.
Prefer pleasant atmosphere and for place to be within 5 blocks of Rock Center.
All suggestions appreciated.
