The title says all that really matters (free margaritas, hello), but here's the complete low-down:

Get down with your fellow riders and celebrate life on the bus!
*Jam to 90s hip hop courtesy of DJ SMA of DEBASER.
* Free el Jimador margaritas!
* Look sharp and hop into the Orange Photography photo booth.
* Munch on free 4505 Meats chicharrones while supplies last.
* All attendees are entered to win prizes from Good Vibrations and Timbuk2
* The Chairman Bao truck will be parked in front of the Make-Out Room! Can you say pork belly?

Well, that sounds like a fine way to start off Saturday night.  6-9pm @ Make-Out Room.  Happy blog bday, Muni Diaries!
