I would think that some places in the Meatpacking, Standard Grill, Abe & Arthurs, Colicchio & Sons - perhaps would be somewhat lively on a Sunday evening. Your best bet is probably to make reservations at one of those restaurants and if it's dead, then you could check out the others. Locanda Verde is consistently packed and would probably still be upbeat and relatively busy at this time.
Good luck on your query.
