Asian bakeries in DC?
If the DC part isn't a strict requirement, here are some options.
Shilla is Korean. Maria's is Chinese. I think all of the Maria's locations use a central baking location.
7039 Little River Turnpike, Annandale, VA 22003
4316 Markham St, Annandale, VA 22003
Maria's Bakery & Cafe
1701 Rockville Pike, Rockville, MD 20852
6799 Wilson Blvd, Falls Church, VA 22044
MattM is unfortunately very right. There are no Asian Bakeries in DC proper and all of the asian bakeries are either in the VA or MD suburbs.
Btw, Shilla is my favorite. I don't know the correct name for this treat, but I love the pastry that looks like walnuts and are filled with a sweet walnut puree and a walnut.
