We had the "small" 10-course tasting menu that was a real treat. The macrobiotic trend seems to be pretty big in gourmet Spanish cuisine, so you could tell that an enormous amount of labor went into creating each dish. Our favorites were the black turnip with veal marrow and the beet gnocchi. The carrot - orange nitro "popcorn" was a little gimmicky, but seemed to be a way to demonstrate virtuosity.
A small note on the service: I gave it an average score not because it was not attentive enough (far from it - our wine and water glasses were constantly refilled, albeit just a few drops at a time), but because we felt rushed. The first course was served within five minutes of us arriving, and they seemed to be brought out every 5-7 minutes, so we were done within less than 90 minutes. This type of meal should be savored, not hurried. Overall, though, a very nice meal and experience that could be even better.
