I've been four or five times (including the opening night, which I'm not basing my overall opinion on), and EVERY time, we were served stale bread--and only after asking several times for the bread. What's with the bread? Seriously? A simple answer might be to just avoid the bread, but it's so basic.
My guess is they're going for the authentic spanish tapas experience. Drove me crazy in Madrid, every place puts stale bread on the table. And on top of that they sneak in a charge on the bill of a couple euros for it. One night I finally got fed up and took the bread out of the basket and started knocking it on the table like Kruschev, telling the waiter, "Es duro!" The old dude looked like he wanted to smash it over my head, but when I told him to take it away and take if off the bill he miraculously came back all smiles with a fresh loaf.
