So my sister just graduated from the baking and pastry arts program at the CIA and is coming to visit me (I live in the Mission) next week. I know next to nothing about pastries and baking generally. I'm much more interested and well versed in cheap ethnic eats, which is definitely not up my sister's alley. The only place I can think to take her is Tartine Bakery (a rec I got from y'all, and which I love.) So I'm looking not only for good bakeries but also cool foodie-oriented shops that I can trot my sister around to. She'll be here for about a week, so the more suggestions the better. Thanks!
