staying in Manhattan or traveling to Brooklyn, Queens, etc.?
off the top of my head:
Sushi Amane (front runner for one of the best sushiya in US?)
Peter Luger’s or Keen’s
Flushing for Chinese food
Fette Sau in Williamsburg for BBQ (haven’t been, but this was recommended)
afternoon snack in East Village at Veniero’s for cheesecake and Hi-Collar for coffee.
