The sea has much to teach us: its tides foretell the lunar cycle, its salt treats us to delicious shark jerky, and its colorful creatures prove that nature looks better in Blu-ray. Celebrate the big salty puddle's sagacity with today's Groupon: for $10, you get $20 worth of seafood at Summerhays Halibut N Chips in Holladay.

Summerhays Halibut N Chips transports the ocean to patrons' taste buds with its Alaskan halibut, cod, shrimp, and more. The menu splashes with ocean-caught fare alongside landlubbering burgers, sandwiches, and fries.

Sample its namesake with a three-piece halibut basket ($12.50), served with french fries (chips, in British parlance) and a choice of coleslaw or salad, or try a specialty sandwich such as the grilled lobster ($6.25, with fries, coleslaw, or salad). Lighter appetites can relish the grilled selections such as the lemon-pepper halibut or salmon fillet ($12 each, with a choice of fries, rice, baked potato, or sweet potato, and coleslaw or salad) or douse a crustaceous craving with a cup of crab bisque ($3.25).
