The Black Friar, Queen Victoria Street EC4. (Opposite Blackfriars Station). Certainly one of the oddest looking pubs in London, very popular though!
The Sea Horse, Queen Victoria Street EC4.
I love the look of this place.
Ye Old Cheshire Cheese, Fleet Street EC4.
A very pleasant building with lots of nooks and crannys, could be a great pub but unfortunately the sheer number of tourists overwhelms it, shame, it's cheap too!
