Yes, that is the Regent on the left. My parents met there too in the late 1940's
The partial sign is for the Golden Galleon pub which was under the Regent. It had a really steep staircase leading to a bar that hosted drag acts. Stumbled down there once when in my late teens. Once was enough.
I believe that Nikola Tesla was on the verge of a discovery that would have meant free energy for all but unfortunately all his notes disappeared after his death.
