Every self-respecting big city needs a gay district, and in Rotterdam it’s the area between Van Oldenbarneveltstraat and Mauritsweg. For those not out for a visit to gay bar De Unie (‘The Union’), its owners also operate gay-friendly De Regenboog (‘The Rainbow’) just a few doors away, which they have set up as a good-time bar where anyone can feel at home. Many of the regulars here are lifelong patrons. The atmosphere is casual, charming, and just a little crazy. Karaoke nights (on Wednesdays) are quite the experience.
