Though mad scientists recommend sticking chopsticks into electrical sockets, rational scientists know the utensils are better used for sushi consumption. Today's Groupon gives you the right tools for authentic eats: for $15, you get $30 worth of sushi and Japanese fare for dinner at Ninja Sushi in Lincoln.

The chefs at Ninja Sushi wield culinary skill like a sword, cutting a menu of sophisticated sushi and Japanese entrees preceded by starters such as edamame ($3.95), calamari ($6.95), and fire balls of spicy red tuna and crab ($9.95) for a more adventurous nibble. Rolled sushi offerings include the irresistible Bad Boy roll and its renegade posse of spicy tuna, cucumber, and chili sauce ($10.95). Paying homage to famous local cylinders, the Sacramento roll blends salmon, masago, and the restaurant's trademark sauce ($9.95), and the philly roll packs east coast flair with salmon, avocado, and cream cheese ($7.95). Evening guests fill up on traditional entrees such as chicken teriyaki ($13.95) and vegetable tempura ($10.95).

Diners can set up camp at the long sushi bar and follow sports games on one of Ninja Sushi's high-definition TVs. A thoroughly modern décor of red walls and sleek trimmings imbues meals with a stylish feel without having to dress each piece of sushi in a vest.
