If humans are mostly made of water, and fish traditionally inhabit water, fish should naturally occur in the human body. Fix this gap in nature's logic with today's Groupon: for $7, you get $15 worth of Japanese fare and drinks at Land of Sushi in Centennial.

Land of Sushi brims with an exotic medley of aromas as diners trawl a sprawling menu populated with schools of sushi, noodles, and tempura. Immerse taste buds in more than 70 sushi and sashimi options, including the lobster tempura roll ($11.95), which basks in golden batter like a sleepy Oompa Loompa. The Manhattan roll ($11.95) stars a cast of snow crab, tuna, salmon, and avocado that romps gleefully across tongue stages. A selection of bento boxes ($9.95 each) satisfies midday cravings with angular efficiency, and beef teriyaki ($13.25) and curry chicken ($12.25) provide toothsome canvases for self-portraits painted in soy sauce.
