Although the café and a-la-carte breakfast options in our hotel were pretty decent, one of the things I always like to seek out when traveling are good third wave coffee spots. London has no shortage and we lucked out by finding the Gentlemen Baristas Coffee House just a few blocks south of us.
In addition to gentlemanly service, the coffee house has excellent coffee and tea, as well as porridge for an unusual (to us) breakfast option. We visited mainly during the week, when most customers were taking their orders away, which left us free to hog a table in the atmospheric brick and wood back room.
