I'm a big fan of Richard Serra. As this is the train station I use to pass in and out of London. I think it's safe to say i've spent more time gazing and contemplating this art work than any other on earth! The steel monolith sits in a rather petite amphitheatre with surrounding step/seats. During the week, it's packed with picnicking stray commuters. I just love sitting there.
Great little cinema, hidden away in the basement of Aubin & Wills, London. Not exactly a fan of the brand but the cinema is pretty awesome. They show a variety of interesting films and have probably the comfiest seats including armchairs and sofas. Bit dear, but one of the best cinemas I've come across.
