As a UCLA undergrad, I would be happy to answer questions about the area.
As far as bars go, you might want to consider going to Westwood Brewing Company or the 'W' hotel (my preference). Both are within walking distance from the law school. If you have the time and energy, you might want to head out to Sunset Blvd. (West Hollywood) which isn't far at all. It would cost about $20.00 to get a cab out there. 10-20 min. depending on trafic.
On Sunset, you could eat dinner and party at Miyagi's. http://www.igougo.com/planning/journalEntryDining.asp?JournalID=20900&EntryID=14522&n=Miyagi's
Go across the street to Dublin's.
Other cool places (On Sunset) include the Saddle Ranch
), Key Club
, infamous House of Blues
, or the bar at the Chateau Marmont
. You could chill out in Hollywood for a week and not scratch the surface of shite you could do there.
Another option you could do is head out to the Third Street Promenade in Santa Monica. Again, it's about a 10-20 min. cab ride depending on traffic. Yet, students frequent these places throughout the school year. The cool thing about Santa Monica is that you would be able to see the beach at third street.
If you come to admitted students weekend, I highly suggest that you do either one or both of these things. Santa Monica could be seen during the day or night, while you should really experience Sunset Blvd. at night. It would give you a good feel about the city and your future living enviornment.
As a side note, you could also check out the Mann Chinese Theater which isn't too far from Sunset if you wish.
If you want some dinning options, just ask, I know some cool places I could suggest.
