Just got back from a long day on the Hill? Tired of hearing about the latest D.C. politician's sex scandal, and just want to tune out from everything? Then just head back to your place and order in your favorite food using GrubHub. It's simple as anything you'll ever use: just search for the type of food you want, and the app will show you resturants nearby that will deliver, or include pick-up options. Order straight from the app using the resturant's menu, pay, and boom—just wait for your food to come. All you have to do is open the door.
