Whatever be requested! We do tend to default to cafes with either rum milkshakes or porn all over the walls in the afternoons and pubs and card games in the evenings, but we know where to find museums and famous landmarks, too! British Museum and Natural History Museums are always worth a look (and are both heated and free) and assuming it's not raining, there's Trafalgar Square, Buckingham Palace, about five million pigeons... And we know how not to get lost on the London Underground, which in my case is an achievement. :D
