London is full of fast food and sandwich shops that offer inexpensive and fresh food. Both Pret a Manger and EAT operate dozens of cafes around the city, with mostly natural and organic foods for take away or eat in.
Perhaps the best way to eat well on the cheap is to rummage through London's many food markets. Borough Market, the city's oldest, is a noisy and unforgettable experience, where you'll find a seemingly unending variety of everything from oysters and olives to sausages, cheeses, vegetables, breads and wines. Every Thursday to Saturday traders from all over the country come here to sell their produce and prepared foods at low prices. Best of all, they encourage taste tests, and proceeds go to charity.
London offers many affordable options for getting to and from the city's airports, each from about 4 pounds. The Piccadilly tube line runs from Heathrow to Paddington Station in the city center. Gatwick, Luton and City airports all have train service as well.
Most major bus lines arrive at the Victoria Coach Station, which is connected to city train lines via the Victoria tube station.
One of the nicest ways to see the city is on a riverboat cruise. Crutchley recommends the Thames Clipper, which runs fast catamaran services up and down the river, stopping at landmarks. A Roamer pass costs about 8 pounds and lets you hop on and off all day.
Save on subway train transportation with an Oyster Card, which will reduce the tariff by at least half. The longer you're in town the better the deal. Children under 18 get a discount, and those under 5 ride free.
Avoid black cabs at all cost.
