When a friend and I took a day trip to D.C., we found ourselves famished after a morning spent in the Smithsonians. She asked me, the navigator among my friends, “Where should we go for lunch?” I pulled out my phone to look at a map, but instead of opening up Google Maps, as my parents might have, I turned to Snap Maps. Snapchat’s map feature was created to share your location with friends, so it’s conveniently equipped with labels of nearby businesses and restaurants.
