It is cold and rainy! Bring a nice jacket.
Protests happen a lot. Be careful!
Remember, they drive on the left side of the road so look the opposite way.
Try the Gordon Ramsay Street Burger restaurant! It's actually very good and not that expensive! Try to book reservations. Sometimes the staff can slip you in if you ask though!
When taking pictures with the British guards, just be respectful.
Check out what shows they have! Sometimes you can get last-minute tickets for cheap.
