I missed the news, and perhaps you did too. Chef Bloise tweeted this four days ago:
@MichaelBloise: As of today, July 23, 2012, I am no longer working at Sushi Samba. I am looking forward to my next challenge.
In a way, this could be good news. Samba is set enough to sail on sans Bloise, and perhaps Michael can get back to doing something more personal.
