A casual cafe tucked away down a little alley off Spui, Zeppos offers sandwiches, salads, and burgers by day and fried fish platters, fondue, and huge shared plates of antipasto by night. Dishes are satisfying, but it’s the lively atmosphere that brings in the crowds. It’s popular, in particular, with students from the University of Amsterdam across the street and has a slightly cheesy decor that’s compounded when the equally cheesy 1980s disco music starts up late on weekend nights. There’s live music every evening except Sunday and kitschy sing-alongs around a grand piano the first Sunday brunch of the month in winter.
