Some things in LA are open late

Sports: Canoga Park Bowl
20122 Vanowen St, Winnetka; 818.340.5190
Hit this 32-lane, billiards-enhanced alley at 4am, and men with satin jackets won't tease your Granny Style.

Cars: Autozone
9350 Whittier Blvd, Pico Rivera; 562.948.3041
No repairs, but the only 24-hour Autozone in LA County does sell everything from replacement headlights to serpentine belts. If your car stalls across two lanes of traffic, singing a tune called "Pushing my Car to Pico Rivera" will give people two reasons to shoot you.

Sun: Supertans
18431 Nordhoff St, Northridge; 818.700.8267
22323-1 Sherman Way, Canoga Park, 818.884.8267
Enough all-night tanning beds (20 in Northridge, 14 in Canoga Park) to ensure that, next time you're out this late, no one will confuse your face with the moon.

Reading: Sherman Oaks Newsstand
14400 Ventura Blvd, Sherman Oaks; 818.995.0632
This just-over-the-hill spot carries over 500 publications, so you can use your insomnia to further your education, or just buy Cat Fancy when no one else is awake to see you.

Clean: Milt and Edie's Dry Cleaners
4021 W. Alameda, Burbank; 818.846.4734
Get an unexpected creamy late-night stain, and Milt and Edie'll turn it around by 8am. Prices are they same as regular same-day service, and they won't even judge you for eating Fettuccine Alfredo off your own chest.

Sports: San Gabriel Valley Badminton (and ping-pong) Club
9255 Telstar Ave, El Monte; 626.307.4650
Though the SGVBC's officially members-only after midnight, you can buy a $7 day pass at 11:59pm and unofficially stay as long as you want. The hitch: lights are on automatic timers controllable only by members, so you'll have to debase yourself to a guy who loves him some shuttlecock all night long.
