La Galerie is a fantastic venue, run by the organisation of the same name. Amongst other things, you can see exhibitions (on the first floor), go to concerts, and enjoy nights which celebrate a particular theme (May Day and traditional folk music, for example). You can even eat here for free on a Wednesday at midday...something to bear in mind!
