I personally dont see anything aside frrom Wayne Manor thats Londonesque. Nolan captured Gotham City as it appeared in the 70's comics, an every city with common building structures, just a bit gritty. The Narrows was the most fantastical of anything in Begins, as said above, like Blade Runner.
Anton Fursts designs for Burtons Gotham City is how it should look for me. It even influenced the way Gotham was presented in the comics after that.
