The carefully rolled nature of sushi makes it ideal for starting snowballs, which is why it’s commonly known as “snowman heart.” Eat to the center of snow with today’s Groupon: for $20, you get $50 worth of Japanese fare at Sumo by Nambara in Leawood.

Chefs at Sumo by Nambara sizzle meats and seafood on smokeless hibachi grills and roll fresh maki and nigiri sushi. On the dinner menu, diners can eat their way upstream over plates of teriyaki salmon ($19) or savor the piquant company of the spicy volcano chicken ($14) before its bad temper earns it a reality-TV contract. Each hibachi-grilled morsel absorbs savory flavor and the cook’s peppery enthusiasm before dancing its way to dinner tables alongside a house salad drizzled with ginger vinaigrette, vegetables, chicken broth, steamed rice, and a shrimp appetizer. Alternatively, diners can graze raw fare from the expansive sushi menu. The Baked Alaska maki roll wraps baked scallops, poached salmon, crab stick, and cream cheese into bite-size bundles ($12), and the Firecracker nigiri’s larger load of spicy yellowtail ($5.25 for two pieces) combusts internally over taste buds, avoiding telltale residual morsels on the neighbor’s lawn.

Sumo’s shimmery drapes, curving booths, and backlit blue rotunda imbue its dining room with contemporary style and a Grover-like color palette. Patrons can also take the air for enhanced digestion in an outdoor seating area. Sumo by Nambara is open Monday–Thursday from 4 p.m. until 10 p.m., Friday–Saturday from 4 p.m. until 11 p.m., and Sunday from noon until 9 p.m.
