I used to visit Winter's in the 60's & 70's quite a lot, usually to get stuff for school - pencils, protractors, compasses and so on.
There were occasions when I popped in to spend my pocket money on other items too. I remember they had a rack in one corner of the shop that sold a book series called "How to draw". So they'd have How to draw - faces, animals, cartoons, landscapes, and such like. I indulged in a few of those.
In the early 70's, the interior became L-shaped after a wee make over.
As for The Chelsea Lounge, well it was a pub I was never in. In fact, I don't recall ever having drank there in any of it's guises, these being - The Drum, City Centre Bar, The Stance & Drum plus the more recent ones who's names I've lost track of.
