There are many activities that should not be performed on an empty stomach, including swimming, surgery, and swimming 30 minutes after having your appendix removed. Acquire acquatic activity fuel with today's Groupon: for $20, you get $40 worth of seafood, sushi, and more at Harbor Docks in Destin.

Scenically perched over the Gulf of Mexico's inviting waters, the seafaring chefs at Harbor Docks whip together tasty treasures crafted from the sea's naturally briny bounty. A parade of ceremonious appetizers opens oceanic feasts with fried crab claws ($10.99+) and fried grouper cheeks ($10.99); stuffed mushrooms are filled with less expressive, but equally delicious lump crab and monterey jack ($11.99). Famished fishermen can sink teeth and hooks into the market-priced catch of the day, culled from Harbor Docks's wholesale market and prepared to your taste, whether you prefer your fish blackened, broiled, sautéed, fried, chargrilled, or converted into a fetching hat. Sushi seekers can take a delectable detour through Harbor Docks's extensive menu of rolls and nigiri, nibbling traditionally prepared bites such as the eel- and avocado-laced Banzai Roll ($8.99). Or rub rice-y elbows with remixed creations such as the Cowboy Roll ($8.99), which corrals hunger using a combination of steak, green onion, and tiny seaweed lassos.

With today's deal, Groupon holders can enjoy the sights and sounds of a shoreline supper from the comforts of Harbor Docks's sunny dockside dining room. Between closing bites of caramelized crème brûlée ($4.99), and white-chocolate bread pudding ($7.99), guests can watch fishermen going about their buoyant business, hauling up nets full of fresh Gulf catches and mail-order mermaid brides.

Reviews

Frommer's recommends Harbor Docks. Though some reviewers are mixed on the service, they praise the sushi and the beautiful view. TripAdvisors give the restaurant an average of three owl eyes, and 15 Yelpers award it a four-star average.

• The harbor views are spectacular from indoors or outdoors at this casual, somewhat rustic establishment. You can order your fill of fried fish, but such specialties as the daily catch sautéed with artichoke hearts are far more enjoyable. – Frommer's
• We went to the sushi side of the restaurant and give it an A+ . We had four orders from their sushi menu and none were a disappointment! – floridamin, TripAdvisor
