Sunshine 27 Restaurant, on the Bowery.
Now, the first sign that this is the place to be, is the fact that it's filled with locals and those Chinese tourist who know where to find the best their culture has to offer. That said, if there were possibly 10 of us Caucasians in a dining room of over 200, it was a lot. So, rule of thumb: when experiencing the cuisine of another culture, go to where the locals go.
Sunshine 27 is a large, bustling restaurant serving Dim Sum, Hong Kong style, with carts. Parties are often seated together at communal tables and the camaraderie is amazing. If you are not a Dim Sum aficionado, sitting with those who are familiar with the cuisine is a great way to learn. As the carts come around, you are offered choices of Shumai, Shrimp Dumplings, and yes, for the more adventurous, Chicken Feet in Black Bean Sauce.
