Yeah true, that's fair enough. And you're right there is good stuff in central especially if you're into cultural stuff (theatre, art galleries etc.) - that stuff is all in central and I absolutely take it for granted, there's only a few cities that can match London for that.
I think I'm just jaded from trying to wade through waddling masses of tourists whenever I make the mistake of going anywhere remotely central on a Saturday or Sunday, but I get why if you're a tourist that stuff probably seems cool
