yeah, that's what we did, and london was great for that, so many things i hadn't eaten, like pastries yeah, and scotch eggs, and quiches were great too
and as a desert jellies and so, yummie
only the underground was rather expensive, not for my daughter, for her it was only 1pound a day, but for me it was often 3 or more, even if we did more than 7km on foot everyday.
but the museums we visited were gratos, that was great of course
