Williamsburg only has a couple of diminutive museums – the City Reliquary and the Brooklyn Art Library – but they're uniquely 'Brooklyn,' and quite unlike anything you'll find across the river. Beer lovers can take a tour at Brooklyn Brewery, a Williamsburg institution, while street-art fans can check out the latest rotation of murals at the Bushwick Collective. Beyond those and a couple of parks, the main draws are the neighborhoods themselves – great places to combine window-shopping, people-watching and bar-hopping.
