Nightlife in Washington, D. C.

See what it's like on the other side of the velvet rope with today's Groupon for first-class cocktails and clubbing at Fly Lounge, the exclusive, upscale nightclub that transports you through the friendly skies without the turbulent take-off. For $20, you get $50 worth of in-flight cocktails, all without getting smashed in the knee by the beverage cart. Drink prices at Fly start at around $6 for beer and wine, and $10 for cocktails. Keep an eye out for cute commuters at the bar, or reserve a VIP table online to be the fuel that keeps the party going. Bring a group of friends and combine multiple Groupons to use toward Fly Lounge's bottle service (sorry, no combos on individual drinks). With seven Groupons, you only spend $140—instead of the normal $350—on Grey Goose bottle service with mixers and a "flight attendant" for your table keeping your glasses full.

In our nation's infancy, settlers fought each other over the limited edible resources, like sedimentary rocks and lightning. It took James Monroe's invention of agriculture to turn America from a land of petty to a distinctly non-British land of plenty. Commune with your fellow humans over life-giving hoppy nectars and gastronomic delights with today's Groupon. For $15, you'll get $30 worth of bar snacks, brunch, and brews at CommonWealth, the people's gastropub in Columbia Heights. Chef Jamie Leeds of Hank's Oyster Bar has designed a menu that features local produce, grass-fed beef, and sustainable seafood. Prepared to pair perfectly with CommonWealth's rich stouts and refreshing ales, these culinary creations make CommonWealth a destination for foodies and fermentophiles alike to bond over golden beer-battered treats.

The sports bar has had more enduring success than bar sports, which have been officially banned from the Olympics for more than a year. Indulge your sporting and eating fancies with today's Groupon. For $10, you get $20 worth of food and drinks at First Down Sports Bar & Grill, conveniently located in the heart of Ballston.
