I'm not sure what you're looking for, but Nightlife is easy to find...
I have a cab driver you can call, he'll tell ya what's happening... "Fast Eddie" 902-6505 He works for the South Strand Cab Co. No answer call 357-4444.
Two attractions off the top of my head would be:
1) Broadway at the Beach (5 or 6 Clubs close together, so it has a good nightlife and shopping during daylight hours)
2) Ocean Annies Beach Bar (This Bar is a nice hotspot right on the beach) 9550 Shore Drive
Let me know where you're staying and I'll recommend some clubs or late night "dives" that serve drinks untill 4 in the morning.
