I'm almost hesitating to post this question because it's so un-specific, but here goes... I'll be visiting NYC on Sunday, probably poking around the downtown neighborhoods -- Chelsea, SoHo, the Seaport area, etc. The weather is supposed to be beautiful, so outdoor dining would be a plus. Is there an Italian place you'd recommend with great food at reasonable prices where folks just seem to be having a good time? High energy yet relaxed; a good place to enjoy the feel of your great city on a great day?
