Two hours north of Barcelona and only open six months out of the year, Ferran Adrià's experimental flagship El Bulli is widely considered to be the best restaurant in the world. So, as you might well imagine, it's rather hard to get reservations and even if you can get them you'll have considerable travelling costs, but for a few hundred dollars each you can get Adrià's El Bulli cookbooks off of Amazon and have fun in your own kitchen. Each hardcover book is "filled with full color photographs, presents not only El Bulli's unparalleled recipes, but also an analysis of their development, philosophy, and technique" and is "presented as a boxed set that includes the main volume, along with a detailed Users Guide and an interactive CD that contains each recipe, numbered and catalogued by year."
El Bulli: 1983-1993, the first volume, is only available special order and at its list price: a whopping $492. Most expensive cookbook ever? I sure think (hope?) so, but if you know differently please let me know.
El Bulli: 1994-1997 is slightly cheaper than its predecessor but still also going for its list price of $450. Third volume El Bulli: 1998-2002 is currently deeply discounted from $350 to $220.50, so if you're an Adrià fan or know someone who is, that probably makes it the El Bulli cookbook to pick up this season.
