I'm already in the habit of taking this little book with me whenever I go to London. You can plan a walk, or just use it as a quick reference, since wherever you find yourself in London it will point you to a great pub nearby. It gives enough information to decide where to drink and also includes some nice photos. But it is not too bulky to toss into a bag or a large pocket. Nice glossy pages so hopefully will stay in good condition despite being carried round a lot.
