A very interesting horeca concept in Moscow is Anticafé Babochki.

Drinks and snacks are free and if you want you can bring in a Big Mac from McDonald's or bring your own sandwiches. As a guest at Anticafé you only pay per minute of your stay instead of paying for consumptions. The Anticafé serves coffee, tea, some other drinks and desserts. All FREE. The light and open café also offers some extras like games, entertainment and of course free WiFi.
