Query: Good Reference Guide

Despite the fact that this book is somewhat out-of-date at thispoint, it remains a good reference guide. I use it as an encyclopediaof airport restaurants. Not only do the entries give information aboutwhere the airport is loacted and what kind of food to expect, theyoften list prices and approach notes, which are invaluable totransient pilots. Some of the information is dated, but for the mostpart, its still useful. So I keep it in my flight bag for those timeswhen I'm looking for a rest stop on the way home from a distantairport.It would be great to have it updated and published as abinder with removable pages, so that pilots can subscribe to receiveupdates (like every other airport guide)...
