It has been confirmed that Izakaya Den, sister restaurant of Sushi Den and now shuttered OTOTO, will be moving into the old Pearl Street Grill location sometime within the year. The move, which will situate Izakaya Den and Sushi Den next to eachother, will allow brothers and owners Toshi and Yasu Kizaki to streamline their concepts. "By streamlining our business we can better manage man power, food cost and other operational cost in order to increase our profit margin," Toshi Kizaki said in an email to Eater. So what will become of the OTOTO space and the Izakaya building? No final word just yet, but Pearl Street Grill, which will reopen as a new concept with a new name somewhere on the street, could be a new tenant.
