My husband is flying in from Boston next week to interview a potential board member. Both he and the prospect are staying at the Waldorf Astoria. He's hoping that some NYC hounds can recommend a suitable place for dinner. Here are the requirements -- excellent food, around $100 per person before wine, quiet(er) atmosphere that lends itself to lengthy discussion, preferably relatively close to hotel. We don't know anything about the prospect's food tastes so the choice shouldn't be too out there. Thanks in advance for any suggestions.
