Spike Mendelsohn shot to fame as a Top Chef contestant and remains renowned thanks to the scrumptiousness of his burgers, fries, and shakes. The Prez Burger (with applewood bacon, onion marmalade, Roquefort cheese, and horseradish mayo sauce) is still the most popular item on the menu, according to the staff; the toasted marshmallow milkshake will always be the #1 milkshake, to my mind. Warning: Good Stuff Eatery is always jumping, with people in line on the first floor and filling upstairs and outdoor patio tables. The line moves fast, and table turnover is fairly quick, but just the same, you might consider getting the burgers to go, as so many do. The pizza place next door, We, The Pizza (tel. 202/544-4008), is also run by the Mendelsohn family. Other Good Stuff Eatery locations are in Georgetown at 3291 M St. NW (tel. 202/337-4663) and at Reagan National Airport (Terminal B).
