I've been to one in SF and one in Mountain View. In SF, people basically showed up, the organizer had pizza (which sponsors paid for - in that case it was WePay and MixPanel), and people just talked and hung out. Very informal. Very low-key.
In Mountain View it was the same story, except for the first 30 minutes or so there was a talk on the evolution of db technology and pros/cons of different platforms.
