Planning a business dinner for ~20 people. Ideally within walking distance of our meeting at 57th St between 6thand 7th Ave. Want a private room. And of course very good food. Given the crowd, need to please a wide range, prefer simple excellence to overly fussy food. Also prefer casual elegance to a more ornate setting. Price not all that important, expecting to spend $150-200 per person all in, need not be opulent though. Looked at Molyvos, which would be just the right vibe/food/setting except it is not really a private room, just a private area and can get quite loud. Any ideas very much apprecaited!
