These days, there a place in SF's Chinatown and on Clement that I like, and usually pick them up from there when the mood strikes. Of course, I always have them whenever I'm in HK & Singapore. I've never gotten a piece too fatty or appeared that it was meant for bacon, and often find it not fat enough. Like I said, I really really like fat!

RE: bitter melon - definitely an acquired taste, but, while it had taken some time, it's sort of grown on me, like those black eggs in congee.

Gaobest - those chicken things look really tasty. I've yet to try that place, and should place it on my to-do list.
