Kiwis in LA and then???

Hi all, two NZ blokes flying into LA for last two weeks of May. Haven't planned any of the trip except for flights in and out of LAX. Where we roam in between those times will most likely be improvised on a daily basis.
Any ideas about nightlife etc? Keeping in mind that one of us is 23, the other (me) is only 20.
Based on suggestion, we will be willing to relocate at the drop of a hat and are pretty much up for anything. Sarging, parties, just hanging out and chilling, you name it.
