The top 10 theme works very well. There are the top 10 sights in Rome (eg. Pantheon, Colosseum etc) then there is a top 10 within each of those (ie top 10 sights at the Pantheon) - with full descriptions/details. It works so much better than the usual rambling descriptions you get in guide books. There is a top 10 Roman foods (Saltimbocca at number 1 - v. good) and wines - and numerous other categories. Full of very good photos and plenty of detail. Fun to use and authoritative. The maps were excellent.The book is very handy - fits easily into a pocket. It was preferable to a larger DK Rome guide which a friend happened to bring, in terms of accessing information quickly and easily. I hope they publish a lot more of the top 10 guides!
