I'm a big fan of London.
I bought it few months ago and loved it. Then I got bored with it. Then I started wearing it to the clubs quite a bit and loving it again. I too like the cognac notes in it and that coconut thing people always notice.
I will admit that sometimes I can detect something very middle-of-the-road in its basenotes, and it reminds me of certain Liz Clai-boring scents. But the top notes pop really nicely and London is a good late night alpha-male type scent. I wouldn't wear it to work, its a "play" scent. It's alot like an Armani scent; similar to Emporio He and Mania.
