Down a dark alley just off the Highway, close to the Tower Hill of London in the East End, is a teeny tiny relic of a music hall known as Wilton's. It originated as an ale house way back in the early 1700s, and soon after was turned into a multi-room venue for food, theater and the like. From mirrors and chandeliers to exposed brick secret stairwells, this one-of-a-kind venue is a must-see. You can go for a show, say a stage production of The Great Gatsby (above), or just stop by the Mahogany Bar for a fancy cocktail with shaved orange slices and elderflower. (Hey, just because it's old doesn't mean it can't be posh.) They also offer weekly tours of the space for those wanting to uncover more "behind the scenes" history.
