Here's one for you foodies that I found through Slate, a review of a visit to El Bulli, the Michelin Guide Three-Star Super Mega Famous Restaurant up in the Empordà. It's food-porn, basically. The diners involved in this meal thought it was excellent, especially given the prices, which, according to them are very reasonable--135 euros for the thirty-course meal, wine not included. You would apparently pay double or triple in Paris. Don't bother if you don't book, like, a year in advance or whatever.
Since I am an amateur eater, I would not waste my money on such a meal since I'd never appreciate it. As I've said before, though, there are many very good restaurants in Barcelona where you can eat very well for less than thirty bucks, wine included. For fresh seafood at unbeatable prices, the places to go are the Puerto Pesquero in Santander and the Viejas Calles in Bilbao.
Coincidentally, here's a story from the Telegraph that says El Bulli is the second best restaurant in the world, down one spot from last year.
