Booze - my go to joint is The Parlor in Santa Monica. From Westwood you just head West on Wilshire for about 3-4 miles. Its a nicer sports bar with a buncha flatscreens all over the joint to catch pretty much any game that is being shown. Crowd wise its predominantly young professionals 25-35 crowd with a bit of the college crowd mixed in. Happy Hour M-F from 4-8 (i believe) with $3 pints on tap and $1.50 gourmet sliders makes for a cheap pre-game drinking spot on Friday. The servers/waitresses there are mostly younger good lookin girls, although there are some exceptions to the rule. Overall I'd say its a decent to good looking crowd except when I am there and I bring the ugly factor up a couple notches.
The Parlor also has a beer pong tournament Wednesday nights, $20/team, single-elimination with cash prizes to the top 3 teams.
Hoop - Cant help you there. I borderline suck at ball myself but enjoy playing and I havent been able to find a regular game to run in. At the local parks you will see a lot of short mexican dudes running up and down the court playing some version of basketball. When I do try to get out and play I will usually hit up this park on Cloverfield and Pico (I think its called Cloverfield Park) but the runs there are sub par. Usually there is 1 court of whites/asians who run up and down but have no sense of bball fundamentals. The other game is usually the brothas and the comp is hit or miss (I dont make it out often enough to get a good read on how the comp is on the regular).
I play over there all the time and you described the courts pretty well. Sometimes it'll be completely empty and sometimes a wait to run full, but thecourts are in fairly good shape and close to Bay Cities for that post-game Godmother
