Haha if you hit a Walmart in LA you know you're in the hood. But if you hit a Walmart ON CRENSHAW get the fuuudge out of there haha.
If you're in Hollywood, I rec you check out LA Live, The Grove, Beverly Center, 3rd Street Promenade, Glendale Galleria, Hollywood & Highland and Del Amo Fashion Center (one of the biggest malls out here). LA Live is amazing, it just opened up next door to Staples Center and theres plenty of stuff (plenty of bars, dinner places, huge movie theater, and the sickest Ritz i've seen in any of the big US cities). The Grove is awesome at night during good weather, people are out, there are bands that come out and all of us hot people walk around haha. The clubs in LA are terrible for guys, you have to shell out some serious coin if you don't want to wait, but as a girl I think you'll be straight. Theres a new club open everyday so I coudln't tell you what the best one is haha. But the popular ones are Area, Les Deux (made famous by the cast of The Hills), Opera, The Standard (shown on Entourage), and Foxtail. If you need any other tips, let me know!
