Here in Seattle we have a group called Saturday House (http://saturdayhouse.org), its a great meeting place, for meeting smart people who are working on great projects. (The tag line is a barcamp every weekend.) Usually at the end of Saturday House a group tends to head out on the town and have dinner at various locations.

Also there is the Six Hour Startup Group that I run, http://sixhourstartup.com which hosts events on Sundays at one of the local bars.

We also have a Startup Drinks organization (Last Friday of every month, http://seattle.startupdrinks.com) and Hops and Chops www.hopsandchops.com (Every Thursday Night).
