Luke Fryer, who owns 13 Wagamama restaurants by franchise in Australia, has invaded NYC with the opening this month of Yushi, a new "deliciously Zen" sushi and bento box spot with outposts at 245 Park Avenue (47th St.) and 250 Vesey Street (World Financial Center). The 47th Street location, which debuts today, has 74 seats and specializes in bento box lunches and dinners, under chef Shaun Presland. The Financial District location opened last week, replacing a branch of Itsu, the London-based sushi chain that set up shop last year in Manhattan. For the new venture, Fryer's teamed up with Spencer Rothschild, who is a co-owner of BLT Prime, Calle Ocho, Django and Rain.
