Deb, we did enjoy ourselves.
DanB, although we didn't use your recommendations, we are grateful for them! We often plan our days around our meals. But in Barcelona due to jet lag, we did the opposite and happened into the nearest restaurant when our bellies spoke up - quite often ones in the Gothic Quarter. And like you, I don't recall the names of any of them, but they were all good. I never did spy the Jules Verne; unless someone else tossed a grenade in there, I believe it may still be standing.
The last night in Barcelona we ate at Moments, a Michelin star restaurant in the Mandarin Oriental Hotel. We had their tasting menu which was very good. My only complaint (if you can call it that) was that the portions were too large for a tasting menu, IMO. They had an optional cheese tasting that I really wanted to try, but I was full - and we hadn't even gotten to the desserts - and when I say desserts, I mean dessertS... "checkerboard of quark and strawberries, then white dessert, and THEN the "eight pastry divertimenti".
One of my favorite parts of the meal was the of "Beef 'salpicon' with capers ice cream" - just one of the four appetizers. Other highlights were the shrimp & tomato velvet ice cream (similar to a frozen gazpacho), and the Norway lobster stew. We also enjoyed the sea cucumbers, sea bass, and veal cheeks. So much good food - so little room in the belly.
