Ooops, sorry Elise, I actually mixed you up with another poster (I was thinking of Ellen who lives in New Jersey). Forgot I gave you some recs regarding Italian restaurants in New York in another thread!
I remember the few years I spent in the Bay Area of California. Salvadoran food, no problem; Mexican, all over the place; one or two Brazilian places, and that was pretty much it for South America and Latin America. I missed the easy access to good Hispanic Caribbean places (Dominican, Puerto Rican, Cuban) that you get in New York, pretty much all over.
Again, the Colombian community is particularly strong in the borough of Queens. Their restaurants are good, too, and very inexpensive.
