Kofusion tries a bit too hard to be hip and edgy. As I am from Los Angeles, where pretentious restaurants are about as ubiquitous as corn is here, it takes more than mood lighting, pseudo-orientalist hipness, and cheap sushi specials to impress.
That said, Kofusion's not *that* bad. It's decent, for what you get. The sushi is adequate, the drinks are on point, and the servers are friendly. Not a bad way to spend a Friday night with friends. Just don't think you're a) being "authentic" or (b) truly hip and classy.
Just enjoy for what it is, a decent midrange sushi place in the midst of Chambana.
