Could you explain what you mean? I've done my best work in coffee shops, hands down. I've also had the most enjoyable time doing it. It's way nicer than a library or an office or a chair at home. When you have a collection of other caffinated people working near you on different projects, you are often more motivated to work yourself. The atmosphere is ambient and doesn't offer much distraction, unless you want it to.

I only get to spend about 3 or 4 hours / week in cafes these days (I have an office job) but those are some of the best work hours I get. I wish I could transition full-time to coffeeshops, and if I get a startup going I might try it.
