Avoid. So much money for so little. I registered for chowhound because it put me and my wife in such bad spirits.
The food wasn't bad, just mostly plain. Most dishes were prepared ahead and tasted like it. The cooked dishes were standard bar food with a weak Spanish flair. The jamon iberico was poorly cut. The wait staff was ridiculously slow.
And then there was the bill. We spent $100 on nothing. I can't imagine what a Spaniard would think of this place, especially one from the south where the tapas are free. There isn't anything authentically Spanish about spending that much on a snack.
Avoid Bar Pintxo if you have to pay attention to how you spend money. If you don't, then go to a better restaurant, go to Spain, or use the money you'd waste on this place to buy some rice for someone who can't afford it.
