United Kingdom
It's a cafe in the middle of Regent's Park's playing fields. So a good place to watch people wearing themselves out whilst you sip on hot chocolate. But also, it has changing rooms, lockers (£1 returnable) and showers (£1.50) which you can use after a run round the park. Plus a schedule of gym classes. Slightly chaotic but all the nicer for it.
