Morning: Market Shopping
For shopping that won't break the bank, head to Old Spitalfields Market where - depending on the day of the week - you'll find everything from vintage clothes and jewellery to arts and crafts. Find out more about London's top 10 markets.
After you've soaked up the atmosphere, grab some lunch at one of the restaurants or cafes lining the market. Or, if it's the weekend, pick up some tasty street food at the Boiler House indoor food market on Brick Lane.
Afternoon: British Museum
Next it's off to the British Museum, London's single most visited museum, featuring exhibits such as the 2,000-year-old Lindow Man, Egyptian pharaohs and treasures from all over the world. Entrance is free so it doesn’t matter how many times you need to go before you see it all!
Evening: British Cuisine
For dinner, make your way just south of the British Museum to Great Russell Street where you will find the Scoff & Banter Bloomsbury restaurant. Discover delicious modern British cuisine and a glass divide between the kitchen and diners, enabling guests to watch the chefs prepare their creations.
Alternatively, there are many restaurants near the British Museum where you will find everything from traditional English to more exotic cuisine.
Morning: National Maritime Museum
The Old Royal Naval College, designed by Sir Christopher Wren, was the site of the Royal Hospital for Seaman and later became a college for naval officers. Highlights include the chapel and the beautiful Painted Hall. (Admission is free, but there's a small charge for tours.)
If you're visiting between Tuesday and Sunday, don't miss Greenwich Market with its unique shops and arts and crafts stalls.
Lunch: Fish and Chips in Greenwich Park
Buy some take-away food from the tempting stalls at Greenwich Market and head to Greenwich Park to admire the view over the whole of London. Or try the Trafalgar Tavern, one of London's oldest pubs, situated on the banks of the River Thames.
Afternoon: Royal Observatory
Stand on the Greenwich Meridian Line, which divides East from West, and explore the history of time and the universe at The Royal Observatory. (Only entrance to the Astronomy Centre is free.)
On your way back to the station, pop into Queen's House. Built by Inigo Jones, it now serves as a gallery for maritime art collections and portraits of the Tudor and Stuart kings and queens associated with its history.
