The word fusion is one of the most misused terms in culinarydom. More often than not, a restaurant will tout itself as a fusion restaurant when in fact all it does is offer two or more cuisines on the same menu. An Chinese restaurant, for example, might also offer some Thai dishes, or maybe a sushi selection. That might be considered diversification, but it isn't fusion.
Fusion occurs when two or more items come together to form something different, something unique.
And as you might deduce from the name, it isn't putting together similar Asian cuisines, though it does work with pan-Asian dishes, but rather a melding of Latino and Asian. The results are refreshingly distinct.
So you might have Chimichanga Eggrolls or Peking Duck Nachos. Or Congri Fried Rice. It's inventive, and even better, most of it works.
