walking from Big Ben to south bank and beyond.The South Bank is an entertainment and commercial district in central London, England on the south bank of the River Thames opposite the City of Westminster. It forms a narrow strip of riverside land within the London Borough of Lambeth (where it adjoins Albert Embankment) and the London Borough of Southwark, (where it adjoins Bankside). As such, the South Bank may be regarded as somewhat akin to the riverside part of an area known previously as Lambeth Marsh and North Lambeth.
