Flutterby™! : coffee shop architectures

This morning I wandered out to get my oil changed, and to find a place to sit and sip a cup of tea and code for a bit. Coffee Roasters was way overpacked, especially since I wanted to sit and type, so I wandered across the street to Javarama, where I overheard a conversation that involved some trust fund baby whining that he was 59 years old and it was so hard to get along on $3500 a month, even owning his house. This got me thinking about various people I've met at both places, and what it is about Coffee Roasters that makes it so much more attractive, even though it's smaller and often feels cramped.

Ages ago Peter Merholz looked at coffee shop design, and I was surprised to find that from the drawings his preferences were exactly reversed from mine. I wonder how much correlation there is between the place and the people it attracts. Any Adaptive Path folks wanna talk about ways to explore this?
