The food was unquestionably very good, of very high quality with thoughtful preparation and presentation. And the service was also very good - a little formal (some of which might have been a small language barrier), but very helpful and efficient (they recommended a wonderful wine - very helpful there). But it was the one restaurant we visited where we were definite in saying we wouldn't go back. It is very expensive and I think you can do better, both at the same level, below and above.
I personally really disliked the decor. Two words - red leather - and a lot of it. Set against a lot of black with very bright lighting - was unpleasant.
Oh, and smoking is allowed in the upstairs dining room, where we were, which was very surprising (banned in Barca in January). I don't mind so much but my friends were very unhappy about it.
So all in all I'd have to say "nah"
