And whilst I'm showing places of (fashionable) conspicuous consumption, here is the interior of Moscow's Philippe Starck-designed restaurant Bon, the third project with that name.
It is, of course, a pretty expensive place to sit down in. But they do a 'Business Lunch' (this English phrase is used in lots of eating places to mean a limited choice of soup/salad/main course at a fixed price) of 800 rubles/£16/$26. This involves ignoring the fact that such 'business lunches' usually cost about 250 rubles.
Or you can do what we did and sit for hours over a pot of tea.
