To Long Beach from L.A. depends on the traffic of the day. You can make it here in as little as 15-20 minutes or as long as 45-60 minutes. Damn traffic.
You can always hit Shoreline Village, Queen Mary, Aquarium of the Pacific, 2nd Street & Belmont Shore for shopping & bars.
You can also head out to Anaheim & go to Downtown Disney for restaurants and shopping.
The Block at Orange is always good too as well as Santa Monica & Universal CityWalk.
