my sister is getting married just outside of nyc next month, and is looking for a manhattan restaurant for the night-before dinner. she's mildly conservative in food (isn't terribly keen on most asian cuisine, has been living in texas for a decade), but can appreciate good stuff, and wants to give out-of-town guests something pretty exciting, downtown, "new york", whatever. we're looking for a place that can comfortably have 15-20 people (mostly in their late 20s/early 30s) for both dinner and drinks/lingering (maybe a place with private rooms?), with a budget of around $30/person (probably not including alcohol). any recommendations/pointers would be greatly appreciated.
