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 $20, you get $40 worth of Japanese cuisine and drinks at Riptide Rockin' Sushi & Teppan Grill in Mission Viejo.

Riptide places diners in an exciting eating environment complete with teppanyaki shows and a menu of freshly prepared sushi and Japanese dishes.

Indulge your stomach's request for delicates by selecting from a lengthy sushi menu, which includes more than 15 specialty rolls—wind your mouth around the lobster roll, an assembly of avocado, cucumber, crab meat, and lobster topped by a scrumptious cream sauce ($15). Keep your chewers in shape with shrimp- and crab-stuffed wontons ($10.95), fire-roasted artichoke ($9.95), and kung pao calamari ($9.95), or customize your culinary experience by opting for Riptide's combo, which offers guests their choice of a main course, a sushi roll, and a side dish ($12.95 for lunch; $19.95 for dinner).

• One of my favorites is the Sexy Mutha Roll featuring shrimp tempura, avocado and radish sprouts rolled with soy paper and topped with spicy tuna, masago, green onion, sesame seeds and sweet eel and cream sauces. – Shawn Pons, OrangeCounty.com
• While Riptide fully embraces the "fun" approach to atmosphere, don't think this is a bad thing where the food is concerned. Huge pink slabs of salmon were draped over a cutting board, just waiting to be artfully prepared. – Miles H., Urbanspoon
