The color blue permeates Maguro’s modern dining room, emanating from the glowing turquoise panels affixed to the sides of the tables and counters, the sky-colored accent lights on the liquor-stocked shelves, and the indigo overhead lights illuminating sleek wooden tabletops and hibachi grills. Here, cooks sizzle up Japanese entrees of meats and fresh fish attractively garnished with sauces and flower-cut veggies. Sushi chefs, meanwhile, coil up a slew of authentic rolls.
