This is a great deal - $15 - and an easy event. I've seen Sara Gazarek before and she's fantastic. I'll let her music speak for itself. Listen: http://saragazarek.com/music/

I haven't been to Seven Degrees, but we've all driven past it. It is a cutting edge meeting center. The seating is unreserved (usually large, round tables). They serve food and beverages and it sounds like simple fare.
What's worked well past Laguna events: meeting for carpooling at a Denny's located at the 5 and Sand Canyon.
Please indicate on your RSVP if you're interested in carpooling. Let's shoot for 5:00 so we can get through the Canyon, park and get seated.
