........and, on the subject of architecture, the GUM shopping centre, Neil........... ???
I typed a longish reply, then I got timed-out by the site server and I lost it :(
Anyhow yes, GUM... large C19th shopping arcade, restored to its former glory now. Lots of pretentious international brands there, but also a couple of nice patisseries with views of Red Square (a nice way to treat guests to the city)... and the old art-deco Cinema Hall has been restored, programming art-house films these days. So not an entirely reprehensible place at all :)
