Someone else mentioned this place (and its beef roll) in an impressive list of good eats, but I'm giving it its own post because it's too good to get lost in a long list.
The "beef roll" is a freshly pan-fried, thin, flaky pancake rolled around thin slices of five-spiced brisket, Hoisin sauce, and cilantro. The textures - crisp/flaky, then chewy, and flavors - salty, sweet, and aromatic, are deeply satisfying.
The dumpling wrappers are the thinnest hand-made wrappers I've ever had. They're fantastic. The dumplings are VERY juicy (I bit into a lamb dumpling and ended up with broth halfway down my sweater sleeve). We had two kinds of fish dumplings, and I definitely liked one better than the other - too bad I don't know which was which.
The house sausage (served cold and thinly sliced) is delicious too - redolent of 5-spice, it's darker and less oily than most Chinese sausage.
