Hack-Day - Themer and Developer play day

I'd like to have a Saturday play day soon. Does anyone have any ideas? I'm thinking anywhere will work: a library, a good cafe, etc. It just has to be a place that is relaxing and all about drupalers and drupaler-to-bes to get together, relax, and chit chat on a friendly level. No pressures, just a place for fun.

THOUGHTS?

If anyone has any thoughts, post them here...
thought:
- The East Orange Public Library [ eopl.org ] ( http://evanced.info/eastorange/evanced/eventcalendar.asp )

WHEN

I figure we can come up with a good date so long as it doesn't land on an event found here: http://groups.drupal.org/events
