Not all light travelers are cheapskates, but anyone who would consider washing underwear in a hotel sink is suspect in all categories. Mea (ahem) culpa.

Actually, in most of the places I stay there’s no shame in carrying in food. For the UK I can suggest a cheap lunch which is available in most areas: the delightful Cornish pasty. At t£1.50 - £3 each they make a tremendous lunch. Pub lunches can be a great value too. The Ploughman’s lunch is filling and wholesome - had one of those at the historic Eagle & Child in Oxford.
In west London the lovely Churchill Arms pub is not to be missed. It contains a fantastic Thai restaraunt with a variety of £6 curry plates - a bargain for London. It has an amazing collection of chamber pots hanging from the rafters, and the exterior of this corner building is usually covered with hanging flower baskets.
