there's a street in LA called Olvera which is super Mexican and kinda cool if you go when its really busy (before or after a dodgers game). Check out Hollywood, go to the beach
especially Santa Monica and Venice beach area. Venice beach is full of hippy's and stoner's selling crappy things they made but its really cool to see.
Thats about it from what i remember. Theres universal studios and other parks like knotsbury but you can figure that out for yourself. Also i probably messed up some of this info so double check it.
