Time Out says
Lausanne's very own beach bar, right in the centre of town.
Open from mid-May to the end of September, this outdoor pop-up bar may be in the central shopping district of Flon rather than by a beach, but thanks to the real sand underfoot it’s possible to close your eyes, wriggle your toes in the sand and imagine you’re on the French Riviera instead. Unfortunately you could probably drive to the south of France for the price of a night out drinking cocktails and spirits here. But if you can put that aside, this is a lovely place to kick off your shoes and lay about on a sun lounger underneath a palm tree, mojito in hand.
