A massive, unique new nightlife space, a former boat hangar beneath one of the monumental stone arches of the Alexandre III bridge, ShowCase is thrilling at its best, owing to its sheer size: there’s room for 1,500 people in its maw. It’s perhaps not at its best on a Saturday night, when swarms of teenagers descend to dance and drink; but if you find yourself invited to an after-party or to see an upcoming band play there, it’s impressive. The sound system is knee-trembling, there’s seating where over-25s can relax, and it’s surprisingly easy to get served at the bar. It’s also the sort of place you might find yourself lured into, during a nocturnal riverside promenade; if you’re after a drink and a dance, you won’t be disappointed but, for sophisticated night culture, keep walking.
