This vast concrete former abattoir is one of Shànghǎi's unique buildings, today converted to house boutiques, bars, shops and restaurants. An extraordinary place built around a central core, its structure is a maze of flared columns, sky-bridges (across which cattle would be led to slaughter), ramps, curved stairwells – and jostling photo opportunities. The shops are not of much interest, but a well-positioned branch of trendy Noodle Bull makes the most of its concrete setting.
