You have to visit L.A. Beaches and relax, try Redondo, Hermosa or Manhattan Beach.
Visit Mickey's in Hermosa for the best sauce sandwich, a great mid day snack.
http://www.mickeysdeli.comTry and hit up Hollywood for a rock show, ie The Viper Room, Key Club etc. Pick up a L.A. Weekly Magazine, they have lots of info for entertainment for Hollywood and Los Angeles Area. They can be found in 7-11s, etc.
http://www.laweekly.com/Take a stroll at Santa Monica Third Street Promenade at night, lots of restaurants, shops, sidewalk performers etc.
http://www.thirdstreetpromenade.com/Got to go to a Dodger Game at Dodger Stadium Chavez Revine. See the schedule and hopefully they are in town when they play. If you are on a budget, they have Pavillion seats in the outfield that I think have all you can eat food (no alsohol served in this area). Night games are great during the summer, perfect weather.
http://losangeles.dodgers.mlb.com/sched ... sp?c_id=laYes, you definately got to go to In'N"out Burgers, get the double double, or if you are really hungry and a big eater, they also do triple-triples, quadruple-quardruples etc (not on the menu, just ask for it). They also can do grilled onions on top (ask for it animal style, again not on the menu).
Those are my ideas. I hope you love L.A. like we do. Have a good time!
