Despite having multiple tents for booze, (they offer a selection of domestic and import beers as well as Jose Cuervo margaritas that do not mess around) it seems that people should never underestimate festival-goers' undying love for getting their drink on.
In fact there were quite a few gems with absolutely no wait whatsoever: La Hacienda, Chelsea's Kitchen, and El Santo (the masterminds who had girls serving tacos in bikinis- well played El Santo, well played).
Another thing that kept the lines running smoothly -- tickets. After paying the $12 entrance fee ($100 if you prefer the VIP treatment) tickets are the main form of currency and can be purchased with cash only (the event is well stocked with ATMs).
Tickets are $2 a piece with one ticket getting you a taco, two tickets getting you menu items that are slightly more substantial, and three tickets getting you the booze of your choice.
