The only DC location of this retro New Jersey–born ice cream and fudge shop is situated on a busy corner in Georgetown which, no matter what the season, is buzzing with ice-cream aficionados—including Barack Obama, who  has visited the shop with his daughters. Try a blend-in, which allows you to infuse different toppings (Oreo’s, Gummi Bears, Reese’s Peanut Butter Cups) into an ice cream of your choice.
