Hing Wang Bakery at 339 Judah Street, San Francisco, California.

Our favorite place for cheap takeaway. The women behind the counter are always helpful, and together we manage to figure out what's good that day. Our favorite is always the sesame balls, just the right amount of savory and sweet, and crunchy and chewy. We've managed to try just all the dim sum by now, and nothing has disappointed. We also enjoy the fried rice and end up ordering too much and enjoying the leftovers later.
There is a table inside, but I've never tried to eat there, it's really just for takeaway.
Can't comment on parking in the area, as I've never tried. It's just a few feet from a stop on the N-Judah line, and close to a few bus lines (6, 66, 43 & 44).
