I had never heard of a restaurant-gym, but that's what the Flying Dutchman is! We just went for a visit, and it's really intended for the nouveau riche Russians. It's the most expensive restaurant in town, with a gym open 24 hours a day, a hairdresser, and pub. Apart from the interior, with the replica three-masted "Amsterdam" ship, built in 1978, it has a terrace where you can spend the hot summer nights. The bathroom is just fabulous, too! It's normally hard to get in, but we were lucky enough to have a connection who arranged things for us.
