I know that this forum is taking on a bit of an air like "An Index to Jonathan Gold's Restaurant Reviews," but that's okay with me until we get more participants - I love Gold's reviews, and this one is no exception. It's worth reading start-to-finish, and will have you craving Mian's style of Zjajiangmian when you're finished.
