Partridges offers a range of American foods in their shops and via online shopping, including Free Range turkeys for Thanksgiving. An international outdoor food market is held every Saturday on the Duke of York Square.
Dates in the UK (and most of the world) are formatted differently than the USA. Instead of Month-Day-Year, the day is first, Day-Month-Year and said for example "the 7th of November" (07-11-2011). Pay attention on important forms and food expirations!
