Before sushi proved how delightful rolled-up food could be, fish had been served folded over rice and woven into a basket. Taste the wound wonders of sushi with today’s Groupon: for $15, you get $30 worth of Japanese cuisine for dinner at Hana.

Hana’s culinary engineers compose a menu of traditional Japanese fare buoyed by 36 creative specialty rolls, delicate sashimi, noodle and teriyaki plates, and a library of sake libations. The Mt. Hood roll pays homage to its towering namesake with a mound of tempura shrimp and crab salad cascaded with spicy salmon and eel sauce ($9), and the Salmon Generation roll reveres the generation that swims upstream, yet later in life returns to where they were born toting dirty laundry and bulky band equipment ($9). A hot dish of beef teriyaki sates red-meat appetites ($11.50), and yakisoba swirls slippery noodles with chicken or veggies onto plates ($7.50). With a collection of five sake classes, each boasting several vintages that vary in taste and finish, a premium sake flight grants sips with which to hydrate a parched craw ($18).
