Club Blue Lagoon is an erotic private club on the Leuvensesteenweg at Kampenhout, in Flemish Brabant between Brussels and Leuven. It describes itself as a luxurious lounge with stylish ladies, and the shape of the place is a bar first: guests drink champagne and cocktails with the hostesses in a lounge, discreetly, and can then use the club's separate rooms.

What it offers is set out on its own site as a short list of "relaxation opportunities" — pole dance, a four-hands massage, body-to-body massage, erotic parties, and, in its own closing phrase, "or that little bit more". It describes the private rooms as discreet and says it keeps a collection of toys, scents and massage oils. Its own photographs show a small red-lit lounge with leather sofas, a dance pole and candlelight, and a set of themed bedrooms it calls love rooms.

It opens seven nights a week on two patterns: Monday to Wednesday from six in the evening until three in the morning, and Thursday to Sunday from eight in the evening until five. There is a large discreet car park, and payment is taken in cash or by bank and credit card. The club recruits hostesses openly and gives a telephone number and an email address for both enquiries and applications.
