I assign to Mordor the grottier, busier parts of London, namely Oxford Street and Piccadilly Circus. I can't understand the attraction myself. The shops there are identical to the shops in other towns in the UK but more hectic. Why do people want to go into chain store hell and suffer for the privilege? And the coffee shops? Starbucks? That wants to go to Mordor too for the prices they charge. Stray just a little from the beaten path in London and you will find some amazing places, such as Soho, Bloomsbury and Covent Garden (not the Piazza though, which is also uninspiring), which are filled with unusual shops, independent cafes and proper pubs.
Plus, Shaftesbury Avenue has nerd central shopping heaven, AKA Forbidden Planet and Orcs' Nest. Bring many pennies...
And while I'm on my rant, I wish people would remember that in the UK we like to form orderly lines at every opportunity.
And there's more... I send to Mordor the business owners who decide it's OK to rip off visitors who don't know the value of the Pound. £4 for
a dish of soup?! And £20 for a bus tour when you can get a number 15 right from Hyde Park to the Tower for £1.50?
