Are you a Russian oligarch with a hankering for some good old-fashioned food from home? Chances are you’ve already happened upon Mari Vanna, a Russian restaurant specialising in just that. Chock full of knick-knacks, the interior design flawlessly calls to mind images of a classical Russian home. There are already outposts in New York, Moscow and St Petersburg, and it’s said to be Roman Abramovich’s favourite place to eat. Needless to say, prices aren’t cheap.
