Since the dawn of humanity, man has longed to conquer the ocean, which is why the invention of the boat was followed swiftly by the adoption of the high-five. Celebrate man’s triumphs with today’s Groupon to Dandy Fine Dining Restaurant Cruise in Alexandria, Virginia. Choose between the following options:

• For $57, you get a Sunday-brunch cruise for two (up to a $114 value, not including beverages, tax, or gratuity). Though champagne is typically available with this package, this deal is only valid for a soft drink.
  
  
• For $95, you get a dinner cruise for two (up to a $196 value, not including beverages, tax, or gratuity).<p>

Glasses clink on Dandy Fine Dining’s multilevel luxury boat as revelers mingle on a 3,700-square-foot outdoor upper deck. For 2.5 hours, the brunch cruise meanders past landmarks such as the Washington Monument, the Jefferson Memorial, and Nationals Park, allowing guests to take home local lore without embezzling from a town crier. The climate-controlled ship floats patrons merrily along as they chatter during a breakfast and lunch buffet complemented by live music. The brunch menu fills plates with salmon mousse, belgian waffles with choice of toppings, and omelets that can be made to order or shaped into a rhombus.

On the weekends, sailing types embark on a three-hour cruise and soak in live music as they dig into a four-course meal. The dinner menu complements the boat’s elegance with selections such as prime rib, a vegetarian platter, or shrimp stuffed with crabmeat. Patrons glide across the ship’s gleaming candle-lit marble dance floor or twirl like a sea captain’s carousel beneath twinkling stars on the open-air deck.
