Before sushi proved how delightful rolled-up food could be, fish had been served folded over rice and woven into a basket. Snack on simple shapes with today's Groupon: for $6, you get $12 worth of sushi and drink at Nippon Sushi and Grill.

Nippon Sushi and Grill's expansive lunch ($10.49) and dinner buffets ($12.99) abound with sushi, rolls, hot dishes, and other delicacies inspired by traditional Japanese cuisine. Nippon's sushi shamans hand-roll specialties such as the Green Dragon roll, deliciously crafted from cream cheese, spicy crab salad, and a fried crab stick, topped with avocado and roe. The cucumber and crab White Tiger roll sports a crown of white fish, tuna, and tempura, and the Ninja Turtle roll's core of cream cheese and crab comes cinched with avocado and a black belt of barbecued eel. Refreshing libations ($1.89) stand by with straws in hand to hose down potential wasabi fires.
