Tall and lean, with an artful tattoo embellishing one arm, native New Yorker Darren Lee Norris looks like a typical nonchef sort of guy in his casual clothing. But looks can be deceiving. Norris is the executive chef and driving energy behind a new Japanese concept in D.C.: a Japanese gastropub, featuring a charcoal-fired grill (the robata), sushi created by chefs from Tokyo, and an aggressively intoxicating sake program. Its name? Kushi Izakaya & Sushi.
