If you've been anywhere near Twitter today, you know that it's #NationalCoffeeDay-a nationwide celebration of caffeination.

To honor the holiday, we're giving a shout-out to some of the must-visit coffee shops using Square across the country. They're all very unique-from Please & Thank You in Louisville, which doubles as a record shop, to Swings in D.C., one of the oldest coffee shops in America.

National Coffee Day aside, be sure to pop into these shops if you find yourself in their neighborhoods. You'll get a great cup year-round.
