I've long been a Moleskine convert, so I was looking forward taking just one book with me on a recent trip to London (rather than my usual tourist map book, Moleskine notebook and address book....). This little baby performed admirably, and I'll continue to use it on future trips to record notes and opinions of eateries, bars, shops and attractions as I experience them.
Downsides? The map is very centrally focused (starting at Kensington in the West), although in its detail I can't fault it. There are also some 'features' such as the tracing paper that obviously looked good in the design studio, but on the ground seem a bit lame. I'm sure future editions will be more practical in this respect.
