Behind Matsuya Sushi & Grill‘s sparkling L-shaped sushi counter, succulent fillets of tuna, salmon, and white fish succumb to chefs’ keen knives before joining rice in bite-sized nigiri or tempting rolls. Avocado and crab add color and flavor to the Rainbow roll ($8.95), and yellowtail and fried scallions pose for spreads in Tiger Beat in the Rock ‘n’ Roll roll ($4.95). Hibachi grills sizzle as a swashbuckling chef taps and tosses mélanges of shrimp and chicken ($14.95), and deep-fried teriyaki tofu joins sides of noodles, rice, soup, and vegetables ($11.95). Waiters dressed in traditional Japanese robes and hats ferry plates decorated with carrot roses and artful splashes of sauce across the dining room, where screens and blond woods cultivate a peaceful atmosphere.

The last Sunday of each month, Matsuya’s chefs unfurl their rolling mats for 50 or more novice cooks during make-your-own-sushi courses. Over the course of four hours, house chefs teach the basics of assembling and slicing rolls into symmetrical segments before students consume their creations and write linked verse about the impermanence of dinner.
