Typically, they'll only accept a drivers licence or passport, but I'm not sure about overseas drivers licence so perhaps a passport is your best bet.
Plus that's only talking Pubs. Anywhere with a late license in London generally operates on the whole "No ID, No entry, you could be 75 we won't let you in." Though I've seen many of my friends from work whom hold German ID such as drivers licenses get by on those so if German, Nordic and French drivers licenses are fine, I would suspect a US one. Just make sure as I said you have ID showing name, picture, date of birth issued by a formally recognized organisation such as the US Government, even if it is only at state level.
