The Courtyard and The Bulls Head appear to have been the same pub. Certainly the building that was once the Courtyard is now a restaurant called India Red, as reported on our Courtyard page. (See photo on Bite (sorry) and Google maps streetview.) Also, the Bulls Head was at 25 Abbey Street, which is the address now of India Red. QED. Please delete whichever you prefer. (I guess the Bulls Head became the Courtyard, but I've lost interest. Erm, apart from intending to take a photo of whichever survives the cull, of course.)
