"DFB" stands for Disney Food Blog,  one of the resources I'm using pretty intensively to prepare for the  family's annual fall vacation this year. (No points for guessing where  we're going.) DFB has published several books -- delivered in PDF form,  and sold directly from the site, in the age-old way of targeted  non-fiction -- and I've bought and read both this one and a shorter,  much more targeted "mini-guide" to the 2013 Epcot Food & Wine  Festival, which will be going on when we hit the World. This book is  updated annually, and covers, as you might guess, all of the  restaurants, carts, stands, and other food-acquisition opportunities in  Walt Disney World -- with both quick capsule reviews of all of the food  locations and lots of themed chapters (where to get a good steak, what  are the best snacks, how to eat healthy, how to work the Disney Dining  Plan, special occasions, dining with kids, best drinking establishments,  sample dining itineraries, and more).I suspect that most of the material in this book originated on the blog, and could probably still be found on the blog with some effort. But I don't mind paying for it, for two reasons: First, it's important to pay for things that are useful to you, so that the people behind those things get recompensed and keep doing them. (If something's free, it's either a hobby rather than a business -- which means it may disappear at any time -- or that thing is not actually the product; you the customer are the product.) Second, assembling and organizing that information in a format that can be read easily offline is a major benefit.
The blog's writing is from the point of view of an enthusiastic and pretty well-versed amateur -- an eater rather than a cook or culinary expert -- and the photography is a bit better than that, with gorgeous views of things that you'll want to eat. It's probably not for top-end foodies -- there's are a few really serious cuisine opportunities in WDW, but many more "good eats" surrounding them -- but both the blog and the book are excellent resources for those of us who want to eat the best possible nosh while we're stuffing ourselves on vacation.
