Via chowhound, I was encouraged to try the Peking Duck House on Mott Street in Chinatown for some really good duck. The peking duck house turned out to be a speck of gentrification along a strip of authenticity on Mott.
I have to say, the duck was delicious, and presented beautifully. I was with four others, and we ordered a peking duck dinner that came with a duck for five, soup, starter course, and 3 other main dishes.
IF I do go back (and take this as a recco for the rest) I would order TWO ducks, and skip the main dishes. I would have been better to enjoy 2 more duck pancakes with hoisen, green onion and cucumber and the delicious duck soup, then eat greasy chinese with the duck. I must say, though, the chili prawns were delicious.
Now, I am looking for a place a little more "authentic" chinatown- someplace with the ducks hanging in the window. Someplace where I might be the only white face in the restaurant and I might have difficulty communicating with the waiter, who doesn't speak english. (am I being too blunt?)
