Every Tuesday in July and August at 20h, concerts on the organ of the Cathedral of Saints Michael and Gudula. In 2000, major organ Gerhard Grenzing were installed in the cathedral. Many national and international organists have had the opportunity to perform there.
The Brussels Greeters are part of the International Greeter network and are made up of volunteers from all walks of life. Many are locals, born and bred in Brussels. Some are expats, passionate about their adopted home. They are historians, architects, designers, foodies and art-lovers, which means you can take a tour with the theme of your choice.
I highly recommend taking the 92 tram from the Royal Palace (Schaarbeek direction) and getting off at Herman Station. This will lead you to Avenue Louis Bertrand, one of the most stunning Art Nouveau streets in Europe! Walk downward halfway until you get to an Art Nouveau-style Italian restaurant (either Le Stelle or Buco di Bacco, which are next to each other). If you have time, walk on the side streets (Paul Deschannel Street, Rogier Street) to discover more buildings.
