What does a tenner get you these days? Three rides on a Routemaster? Six litres of premium unleaded? Two and a half Tesco meal deals? Six Oysters and a glass of Prosecco? Yes beleaguered Londoner. All of those things. Especially the last. At least, if you shimmy your light-pocketed person down to Little Water Covent Garden, it does. One of the best foodie hangout spots in town, snap up a ticket while they last. Over 18s only. Valid ID required.
