Small, unassuming and unmistakably old (1665), Café Pieper features stained-glass windows, antique beer mugs hanging from the bar and a working Belgian beer pump (1875). Sip an Amsterdam-brewed Brouwerij 't IJ beer or a terrific cappuccino as you marvel at the claustrophobia of the low-ceilinged bar (people were shorter back in the 17th century – even the Dutch, it seems).
