Is there a dress code for Chez Clément Thursday disco nights?

The Thursday disco nights do not enforce a dress code. The brasserie is a public dining room that turns into a dance floor over the course of the evening; both modes call for the same broadly smart-casual register that suits a Belgian brasserie meal on any other day. You can come straight from work in office clothes, in a shirt and jeans, in a dress, in trainers, what matters is that you are at ease for an evening that may start at the table and end on the dance floor. The crowd reflects this: regulars from Genval, La Hulpe and Rixensart turn up in a variety of registers, and no one looks out of place.

What the brasserie does ask for is the general tone you would expect from a 230-seat restaurant in business since 1858. Beachwear, swimwear, very obviously stained sportswear or a state of dress that would clash with a brasserie dinner are not appropriate. Outside of those very loose limits, you have freedom. The Thursday-night audience is mixed in age, from late twenties to early sixties is the usual spread, and the music selection (disco, funk, soul, feel-good party tracks) does not demand a particular look.

Special touches are welcome, not required. Some regulars enjoy turning up in a disco-style shirt or a pair of sequins as a wink to the format; others stick to a clean smart-casual outfit. Marie and Gilles Verleyen, the fifth-generation owners since 2021, run the Thursday nights in the same spirit France Clément set in the mid-1990s, convivial, welcoming, broadly classless, with no theatrical entrance requirements. The brasserie's culture is that of a family-run public room, not of a club with a list.

If you are coming as part of a larger party with a theme, a birthday, leaving drinks, a fancy-dress moment, a quick heads-up to the team on +32 2 652 33 92 is appreciated, so the staff can position your group well and avoid a costume that might startle the room. Otherwise, just turn up as you are.
