What’s the safest cuisine for those avoiding burnt-bacon-and-peanut-butter sandwiches? Japanese! Mayor Bloomberg, who lately has been drawing attention for his often unhealthy dietary choices, was spotted Wednesday night consuming lighter fare at Hibino, a Japanese restaurant on Henry Street in Brooklyn. Hizzoner was holding court in the middle of a table of some 10 staffers/voters/admirers. No word on what he ate, but one of the daily specials was gobo-stuffed fishcake. Yum!
