Although KoFusion claims to sell only wild-caught seafood, this is not true. For example, they serve Kona kampachi, which is the brand name for a fish sold by a farm in Hawaii. On top of that, they do not label which fish is farmed and which is wild. So, the only thing you can do is ask. And, I would also ask whether the meat you're ordering is actually organic, because if the restaurant is willing to mislead their customers about the fish, I wouldn't trust them about the meat either!
Why anyone would want to patronize a restaurant that has so little respect for the customers that it lies to them about about what's on the menu?
