That's a shame, I was hoping for a pozole blanco/pho mashup. I feel like that should really work. And carnitas on banh mi would be fantastic. The coffee culture would probably also be excellent.
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.
If you ever want some sort of fusion culture, the only places you can discover that tend to be the US or Canada.
There are some Mexican fusion places in Saigon, but they are extremely overpriced and mid.
