yeah, whatever baggss have said... but the only problem i forsee over SF would be traffic and parking spaces, if your planning on driving. i would recomend a compact car for that city, since its somewhat on the crowded side with small streets and parking spots.
if you wanna try a nice restaurant by the beach in LA, try Gladstones. Are you into museums? Getty Center in LA is nice, and so is La Brea Tar Pits. If you want a fancy shmancy restaurant over a hill overlooking the city lights, Castaway in Burbank is where to go. Not too expensive and the view is pretty nice. You dont even have to dress too nice to eat there. jeans, button down shirt with brown, or black shoes will do. as for your wife, a nice sunday dress is good. Over in SF, just eat along pier 39 restaurants. theres lots of them in there. Also, do the alcatraz trip if your into history of the alcatraz. oh i forgot, if your into extreme roller coaster, six flags in Valencia, just north of LA, is the place to go. Skip Knotts Berry Farm. i cant think of anything else, but if i do, ill post them up.
also, try this link...
www.citysearch.com and just look up some stuff on that site. its pretty helpful and it gives you some info on whatever your looking for. Oh yeah, since the weather around that day that you are visiting is pretty nice, try a romantic "dinner" in long beach. try Gondola Ride of Long Beach.
