For bakery AUs, I can recommend luciazephyr's "Stars and Stones Bakery and Coffee Shop". Dresden Files, AU obvs, Harry/Marcone. Searching for "bakery" at AO3 gives a few AUs, Potter, SGA, etc. There are also a couple of barista AUs I've read recently that I don't have the links handy for right now but I can try to find if you're interested.
