What first-timers get wrong in Brussels
Contactless tapping on STIB caps automatically at €8.50 a day, so buying a paper day pass is usually pointless. Avoid any restaurant on Rue des Bouchers with a man outside offering you a table. The city is officially bilingual and street names appear twice, so Bruxelles-Midi and Brussel-Zuid are one station. Sunday brings the Marolles flea market and shuts much else.
What's actually worth your time in Brussels
The Grand-Place earns its reputation, particularly after dark when the guild houses are lit. Manneken Pis is smaller than every photograph implies and takes ninety seconds. The Atomium charges a real ticket for a view that reads as industrial rather than beautiful. The Royal Greenhouses at Laeken open for roughly three weeks each spring and are sealed the rest of the year.
Brussels's museums, and which one to pick
The Royal Museums of Fine Arts and the Magritte Museum share one building and one free window, the first Wednesday of each month from one o'clock, and both close Mondays. The Musical Instruments Museum occupies the Old England art nouveau store and issues headphones that play whatever you stand in front of. The Comics Art Museum sits inside a Horta-designed warehouse.
Brussels with kids, realistically
Metro stations have lifts, but Brussels is steep between the upper and lower town, and the free Ascenseur des Marolles removes the worst of the climb. The Comics Art Museum, Mini-Europe beside the Atomium and Train World in Schaerbeek all suit ages five to twelve. Low-floor trams take prams, under-sixes travel free, and the Bois de la Cambre has a rowing lake.
When the weather turns in Brussels
The Galeries Royales Saint-Hubert, glass-roofed since 1847, let you shop and eat without a coat. The Fine Arts and Magritte museums connect internally, so one entrance covers both. The Musical Instruments Museum's rooftop cafe looks over the city from behind glass. The Horta Museum in Saint-Gilles, the architect's own house, is an interior in every sense and closes Mondays.

Where to base yourself in Brussels
- Grand-Place — Gothic centre — the medieval square, chocolate shops, the city heart.
- Saint-Géry — Hip nightlife district — bars, late-night cafés, the most-Insta-ed strip.
- European Quarter — EU institutions side — calmer, museum-heavy, weekend-quiet.
