Query: Seriously out of date.

When we last visited Hungary in 2011, this book was already listing hotels and restaurants that were no longer extant. Having kept up with friends over there, we know it's now seriously out of date. Even a number of important streets and subway stations in Budapest have changed their names, and the list of changes in secondary cities and towns are huge. Good as this series has been, it needs a serious revision to be useful in the future. If you want to stick with Budapest, go with the Lonely Planet Budapest guide, but if you're looking for something better on Hungary in general, look elsewhere.
