Inside L&T's flagship department store in Osnabrück, tucked into a roughly 5,000-square-meter sports annex, sits an indoor standing wave locals call the Hasewelle—a CityWave-style setup that lets you surf without ever leaving the building. It's an odd, very German bit of retail theater: shop for boots upstairs, paddle a man-made wave downstairs. Hours, pricing, and booking details aren't widely published online, so your best bet is checking with the store directly before a visit. It's more novelty stop than destination session, but it's a real wave—and a genuinely strange one to find inside a shopping mall.
