I think its typical to a “shanghainese” breakfast. Basically I’m looking for good chinese donuts (the long deep fried dough sticks), and “dow jeung”, which is fresh warm soy milk you can order either salty or sweet. The salty (which I prefer) is usually served with chives and sometimes with chili oil. You dip the donuts in the warm soy milk. YUM!
When I was growing up in the SF area, I ate this all the time so I thought it was very common, but after several years in NYC I don’t know where to find it (but haven't looked very hard either). Now I have an intense craving so any help is appreciated!
