It's difficult to overstate the benefits of coffee, though experts believe that with enough caffeine, science will one day be able to. Try your hand at hyperbole with today's Groupon: for $5, you get $10 worth of coffeehouse fare at The Coffee Roastery.

The Coffee Roastery, featured on CNN, houses a crack team of baristas who draw from an arsenal of coffee beans from across the globe. Guests can get wired beneath the elevated ceilings, go wireless with the complimentary WiFi, or take inspiration from the multi-media artwork and shrines to Shaky, the Norse god of coffee. Percolation professionals drip the darkened elixir in blends from around the world, filling mugs with a straight black brew from Guatemala ($1.70 for 16 oz.), putting a foam cap on espresso from Cameroon ($2.85 for 16 oz.), or stirring chocolate in with Sumatran beans ($3.50). Fill deserted stomachs with a variety of New York–style cheesecakes ($2.95/slice) or one of the rotating flavors of freshly swirled soft-serve ($2.95+).
