With booze, cakes and chocolates out of the way, it's time to feed your brain. London boasts many institutions that offer courses on everything from sculpting to gamekeeping, but you can also learn a thing or two about the city itself.
Bishopsgate Institute contains one of the capital's premier local history libraries. It also puts on a number of courses to help you get better acquainted with the city.
