LA locals willing to help out some East Coasters during Long Beach?

[Silverbullet]

Hey fellow Zilvians on the other coast. Some friends and I are making our way to LA on April 12th weekend, and catching Formula D on Long beach will be one of our to do things.
Not having ever been to LA, I come to my Zilvia family to see if there are any locals willing to help out some East coasters in finding must go to places to check out, dine, and party at in LA.

-In terms of partying, preferably places/areas that are dance and house music friendly
-Food wise, anything that isn't burgers, hot dogs, and pizza!
-nice spots on the beach (Long , Huntington, and Newport Beach)
-Whatever else you can recommend. We have no idea what we're looking for, tell us what a bunch of 240/car guys from the east coast would like, LA!

I understand Coachella, as well as NPPL Huntington Beach Open (paintball) take place during this weekend as well and may very well be destination options for the weekend.

Throw out any ideas, you have no idea how idea how much this would help us not going into a city blind. I'm very much obliged for making new friends and buying drinks!
