I've just started shopping at Trader Joe's, and I'm liking it. I never went before because I live in Mill Valley, and the closet one is in San Rafael, and I just can't deal with the small parking lot and store. But now there's a nice new big one in Novato, so I've been going there. (And soon we'll get one near Cost Plus in Corte Madera, so that's good.) Anyway, I'd like to know what people's favorites are (especially in the frozen and prepared foods categories) as well as things to avoid. I notice that Trader Joe's items often get low ratings in the SF Chronicle's taste tests, so I want to figure out how to just buy the good stuff. Today I noticed some shu mai and potstickers in the frozen section. Worth buying?
