The clenched expressions say it all: school holiday time. Increasingly, London restaurants are wising up to this fact by putting on child-friendly initiatives, such as the striking Rocket Riverside in Putney. Pizza playdough, games and toys and an open-plan environment all help with the toddler-taming, as does a menu with children's main courses at £4 a pop. Choices feature the usual childpleasers: fish and chips, sausages and mash, a selection of pizzas and extravagant sundaes. They're also quite happy to make small portions of anything from the main menu. Rocket Riverside, Brewhouse Street SW15. Tel: 020 8789 7875. Tube: Putney Bridge
