On my recent visit to Barcelona, my partner and I visited this lovely spot. In fairness, the first time we attempted to visit it was too busy, so I recommend making a reservation or going a bit earlier. We then came back the next evening on our way home from a days activities.
We are very glad that we did, the food was top class. We had a variety tapas from Calamari to Potato Bravas, then dessert, coffee's and wine. All of which were some of the best food we had when in Barca. The food was fresh and full of flavour and the waiter was polite and courteous.
Into the bargain the meal was one of the cheapest we had, and with its central location this very much shocked us. Couldn't recommend this place highly enough.
