Sushi gained popularity during the age of the samurai due to its portability and the katana-sharpening properties of dry seaweed. Enjoy some multi-tasking nourishment with today’s Groupon: for $15, you get $30 worth of sushi, steak, and seafood fare at Restaurant Tora.

Restaurant Tora's elegant dining ambiance and menu of substantial Japanese dishes have procured the restaurant a place on NBC-4’s 2010 Best of the Best Restaurants list. The sushi sampler fills chopsticks and between-joke silences with two pieces of tuna, salmon, and yellowtail and three samplings of the california and spicy-tuna rolls to form a tasting tour of artisan rollmanship ($17.99). Steak specimens include tender cuts of filet mignon—an eight-ounce center-cut flank served beside miso soup and garlic mashed potatoes ($23.99)—and seafaring stomachs feast upon shrimp ($18.99), scallop ($18.99), or lobster hibachi ($21.99) with vegetables. Diners seeking geometric provender will delight in the menu of box and dodecahedron entrees brimming with salads, spring rolls, six california rolls, and centerpieces such as chicken hibachi ($19.99).

Inside Restaurant Tora, white-clothed tables contrast with elegant black seating and phosphorescent cutlery. Intricate modern chandeliers swathe diners in subdued lighting as chefs perform feats of culinary wizardry at the open sushi bar.
