Foster's is a joke... It's brewed in Canada, first of all, and secondly, I know an Australian, and she says never seen anyone there drink it. Her observation is confirmed by other reports. Then again I drink Coke and am below the legal drinking age here so...
I think Corona is like the Mexican Foster's or something. It's weird, I don't think any self respecting Mexican would drink it, but it's like the only thing Latino immigrants and their descendants here in LA drink, except for one I know who drinks St. Pauli Girl.
