For those who don't like the hustle and bustle of coffee shops, may I suggest university libraries? They're quiet, generally unattended by the local undergrads, and the wifi is generally very consistently available (even if there is a registration process to make sure your machine fits school security standards). Plenty of power, too. On the downside, there's no cheap coffee nearby and sometimes it isn't allowed at all. The same may go for parking. Still, if uninterrupted peace and quiet is what you need for productivity, they may be a solid option.
