I'm a non-New Yorker, non-Chowhound, trying to plan a birthday dinner for 4 middle of next week. My girlfriend's an NYCer and a Chowhound, so I'm feeling intimidated. She's not a big fan of Asian food, but otherwise cuisine doesn't matter so much as long as it's a place with really delicious, fresh food and a fun atmosphere. I was thinking of something downtown, maybe around Tribeca. I haven't narrowed on cost b/c I don't know the market well enough and it's a special occasion. Any help would be greatly appreciated. Please tell me your favorites! Thanks.
