Maybe you should update the guide. 41 degrees is not a cocktail bar any longer and hasn't been for quite a while. It is a fine dining establishment a total of 16 guests/night are served 50-60 small dishes that together forms a tasting menu of 41 servings.
It is truly spectacular, advanced techniques etc. The Adria brothers sure know how to cook! (And that is probably a great understatement). For those millions of you that never did make it to El Bulli, hurry up its still quite easy to get a table here!!!
They are planning to build a completely new restaurant around this concept in the building next door.
