We were on our first visit to San Francisco in 2009 and were walking along Grant Ave. in Chinatown. We were wanting to have Dim Sum while there. A older lady was standing on the corner advertising for Hang An tea room. When we said, yes, we would like to try it, she took off up the hill toward the restaurant, which is tucked down a small alley next to a playground. We had a hard time keeping up!
Hang Ah is tucked away down a alley next to the Willie "Woo Woo" Wong playground. Seriously. It's decor is a combination of worn yellow and lime paint. That's not a putdown. It has the kind of "character" we like. It also had what appeared to be older pictures of Asian beauty pageants around the room, which added to the kitsch factor in a good way.
The dishes we had were all good. I tried chicken feet for the second time but it's apparently just not my thing. I would certainly return here anytime we were lucky enough to be in Chinatown again.
