Nintendo is teaming up with London's Metro magazine to provide free taxi rides in London!

To celebrate the launch of Mario Kart: DS, Londoners will be able to get free cab rides in Zone One this Friday, in ten Mario Kart branded black cabs which will be in service for one day only!

The way it works is simple: just check Friday's edition of Metro magazine for an exclusive voucher then hail any one of the branded cabs for a free ride in Zone One!

This news comes from an article in today's copy of the Metro - big thanks to Revo-Europe reader Ricardo Gallardo for sending it in.

Updated: So, anyone claimed a free taxi ride today? We can now bring you a scan of the article for you to see:
