Here are a few tips:
I would strongly recommend against drinking and then driving on NYE as checkpoints are all over LA
. Taxi wait times usually are upwards of 45-60 minutes on average starting from about 7p for New Year's Eve. Keep in mind traffic here totally sucks after 3p on any given week day, so do plan accordingly. If you want to do the Hollywood Nightlife NYE (which is always awesome every year ), book a room at the W Hotel located on Hollywood Boulevard and Vine. From there, have dinner at Katsuya (Sunset Boulevard and Vine), and then you can simply walk approximately 5-10 blocks total to various night clubs.
Also, use Beverly Hills Cab 310-273-6611 as they are the least expensive in LA
. You need to have the exact address of your pick up point. When you enter your cab, be friendly, tip WELL, and ask for the driver's phone number. Not only will he remember you, but he will do everything he can to get to you quick thus avoiding the queue for taxi pick-up!!! For a $10 cab far, I always tip $5 or more depending if I plan on using a cab again. You'll get the best service ever!
If you want something not as crazy, but on the trendy, classy side, go to "Villa Blanca" on Robertson Blvd (just north of Melrose Avenue) in West Hollywood. When you are finished at Villa Blanca, walk up two blocks to "The Abbey" - this place has great music, good-looking crowd, strong drinks, and never a cover charge! This place is my usual go-to hangout.
New Years Day, drive over to "Belmont" for their delicious bloody mary bar to cure that hangover!!!!!! =]
Bon Voyage and enjoy your time in Los Angeles!!!!!!!
