Coffee continues to be the most efficient fuel for the human body's complex system of fuel injectors, auxiliary hearts, and flux capacitors. Fill up your tank with today's Groupon: for $10, you get $20 worth of coffee and café fare at Jo's Hot Coffee and Good Food. This Groupon is only valid at Jo's West Second Street location.

Jo's whips up a menu of scrumptious sandwiches and burgers alongside numerous coffee drinks that span the caffeinated spectrum. Sample one of Jo's famous burgers, available in such incarnations as the chili cheddar burger, a 100% Angus beef patty slathered in a bed of Jo's house-made chili and fresh red onions ($8.50). Or grab a sandwich ($6–$9) such as Joe's Cubano, an edible island of slow-roasted pulled pork, smoked ham, swiss cheese, and pickles, served on a sweet bun with an equally personable smattering of whole grain mustard ($8). Visitors can bookend their day by dropping in for a breakfast of blueberry pancakes ($4.50–$6.50) or chorizo-stuffed breakfast tacos ($3), and then again after dusk to delve into homemade brownies ($2.50) or banana nut bread ($2.50) before drifting to dreamland. Drinks range from brewed coffee to Mighty Leaf tea, with a full array of café-style caffeinated drinks such as macchiatos, espressos, and cappuccinos. Sippables can be sweetly customized by adding any combination of flavored syrups––such as blackberry, caramel, or toffee crunch––or by having the cup engraved.
