Supermarkets in East LA may be the most racially segregated places I have ever been. Within about twenty minutes of my apartment it is possible for me to be the only White person in a store full of  Chinese/Japanese/Vietnamese(Rosemead or Alhambra), a store full of Hispanics(Pico Rivera), a store full of Indians(Artesia), or a store full of Black people(I haven't yet tested this, but Compton isn't far so they must exist).

You can get some pretty amazing stuff in East LA though. In my last few weeks of searching I have encountered: Venison, Quail, Partridge, Pheasant, Squab, Wild Boar, Armadillo, Ribbon fish, live and frozen Abalone, Live Prawns/Shrimp, Live Snails and Conch,  live Turtles, live Lingcod, Betel leaves, fresh Durian, fresh Jackfruit, along with dozens of other fruit vegetables and fish I had never seen.
