When people mention Japanese breakfast in this town, we don’t know if they’re talking about the Philly-based alternative band or getting a roll from Kei Sushi before noon. This spot in Center City opens at 11:30am which means it’s a great place to come and ditch the office for a long early lunch. The space is pretty small, so it’s easy to relax at the sushi counter and watch as mackerel, hamachi, hirame, and salmon belly all get plated for the handful of families and people on first dates inside. Come here for a few handrolls full of chopped spicy tuna and chunks of crab meat, a few orders of pork gyoza soup, and the silky black sesame mochi ice cream for dessert.
