I've been to different types of (quite excellent!) fusion restaurants in both Peru and Colombia, not to mention multiple cities in Mexico. Good, creative cuisine that draws from multiple cultures is most definitely not limited to primarily a US/Canada thing.

I've been to the Loro[1] in Austin, and I was fairly impressed.

Do you know a specific place in either Anaheim or East SJ that has it?

Tippy's!
