//Wetherspoon's have largely followed the 'pizza and burgers' route with their menu these days, presumably to meet the demands of families with children and younger diners.//
I think you're right, Chris. I've been using JDW for many years, usually for "lunch" with a group of friends in Central London but sometimes locally. I can recall some years ago, the Steak Night offering included two steaks and a bottle of wine for £15. That went many moons ago.
I have to agree that the standard of 'Spoons outlets varies enormously. In honesty, it's usually the clientele that make the difference. I have two near me - one is a dump which attracts all manner of waifs and strays, the other is quite nice. I've noticed that feature in a number of towns which have more than one Wethers - one good, one not so good. Chesterfield springs to mind. The Portland Hotel is very nice; the Spa Lane Vaults, no more than half a mile away, is a dive. Two worth a visit purely for architectural reasons are The Winter Gardens in Harrogate and the Royal Victoria Pavillion in Ramsgate.
