The South Bank has always been London's pleasure zone - from the den of actors, prostitutes and bear-baiting in Shakespeare's time to the 1950's South Bank Centre of theatres, concert halls, galleries and cinemas. It's a pleasant walk from County hall opposite the Houses of Parliament to Tower Bridge in the East. See our Walks section for further details. The Tate Modern is simply too busy to visit at weekends, but well worth the trek in the week.
There is very little to see further than 100 metres south of the river. The London Eye and the Aquarium are the chief manmade atractions. The river is the main natural one.
Eat at RSJ near the South Bank centre or any of the restaurants that cluster round Bermondsey St (Delfina, Bermondsey Kitchen, Magdalen) and Borough Market (Brindisi) in the Borough south of London Bridge, Tas on The Cut, or more informally in Gabriel's market near the 'OXO' tower. There's a whole parade of restaurants packed next to each other just east of Toweer Bridge on the Riverside. Tubes: Waterloo, Southwark or London Bridge.

You might like to look at this site, maintained by the Development agency and Employers' group - it has interesting walks and good colour brochures (these may be picked up at several sites on the South Bank - the Cafe of the NFT is the best).
