The Sunshine General Store (located in Brookeville, MD, on the corner of Georgia Ave and Rt. 650) is probably not a place most people would consider stopping for, if they weren’t aware of the burgers that are made inside.
The sign on the door will remind you that cash is the only form of currency accepted. “Probably Olney or Laytonsville” is the answer you’ll hear if you ask where the closest ATM is. Update: They now accept credit cards.
