Okibà means "here it is" in Neapolitan dialect. The first Okibà opened in Rome four years ago.
The extremely popular restaurant in Los Angeles, Mozza, was "inspired" by Obikà as were several other high profile restaurants in the States after their owners visited the Rome restaurant.
Now the owner, Naples native Silvio Ursini, is expanding. There's already one in Milan and another recently opened in New York City. Here is the article from the New York Times: http://www.nytimes.com/2008/09/17/dining/17mozza.html?_r=1
I've only been to the one in Milan but I'm excited to check this place out.
