I know, this is going to be a tricky one -- but that's why I can't figure it out myself!
I've been craving a "real" Chinese breakfast of the kind one can find pretty much anywhere in SF/LA -- or, let's be honest, China -- but I'm also a vegan without a car living in Washington, DC. And a native Chinese, so I have high standards -- Ping Pong Dim Sum is not what I'm looking for.
The lack of car thing isn't a huge problem -- I'm absolutely willing to bike 10 miles from a metro station for a Chinese breakfast place with great vegan options: fresh (not frozen) steamed red-bean and taro buns and rolls, hot soy milk, "fried dough", sesame pan-fried cakes, scallion and taro pancakes, and of course hot salty congee with (non-meat) mix-ins.
I'm appealing to the collective wisdom of Chowhound for a solution to this puzzle. Hours of poring Google and vegan message boards has done me no good.
