Asked where to get good Chinese in the Mission, Drew answered:
For good Chinese takeout I go to Hung Yuen on 22nd between Bartlett and Valencia. Their trilingual (Chinese-English-Spanish) menu is very amusing, and the food is quite good. You can even watch Hung Granny making the pot stickers by hand.
Link. I’d like to meet this Hung Granny. I think I’ll go right now.

This place is not clean. Indeed the pot stickers are good, but she makes them in the dining room, on a table from a mound of meat, its disturbing… http://cleanscores.com/169468/HEUNG+YUEN+RESTAURANT has the official goods if you want to check it out.

Sadly I can’t recomend based on the one time I ate there. Not horrible, but this is a greasy, economy-type place that seemed to have a mostly Spanish-speaking customer base.
