Candles burn even during the day at this bar based in a mid-16th-century house, which is one of two remaining wooden buildings in the city. The name allegedly comes from the bar's role in the 16th and 17th centuries as a crash pad for sailors from the Far East, who often toted aapjes (monkeys) with them.

Vintage jazz on the stereo enhances the time-warp feel. The place is stuffed with advertising signs and plenty of locals.
