When you’re done geeking out over Songbyrd Café’s 1947 Voice-O-Graph, step up to the counter and order a Frankenfood of DC snacks dubbed the Mumbo Slice. The chef tops focaccia with mumbo sauce, chopped pork, pineapple, Provolone, shaved onions and basil for a hearty bite. Though there’s no beer to pair with pizza or all-day breakfast sandwiches, there is coffee and a stack of vinyl to thumb through and purchase. You can opt to plug into iPads made to look old-timey or take a seat in the “conversation pit” styled with seats that should remind you of Charles De Gaulle Airport. Expect to leave and immediately phone your coolest friend to say you’ve found a place they’ll love.
