Let me know if you want an intro to them (email is in my profile).
Right now, I'll usually take a laptop to a restaurant or cafe... Starbucks is not the place to do this, usually. too busy, and they are setup to move people in and out quickly. (they have an interesting business model... basically be kindof like places that loose money being a cool place to hang out, only without the expensive space-using 'hanging out' part.) There's a 'bubble tea' place near where I live that I like, they aren't busy and the owners seem friendly, and they don't seem to mind me being loud while working with others. they aren't open late, though. and I've got to bring my own network. and no external monitors or anything nice like that. (really, I can't work for more than an hour or two on a laptop without tweaking out my back. External keyboards and monitors solve the problem)
