The common thing to do in Spain is order tapas – small plates of food. They are either served hot or cold.
I recommend La Flauta . We had a tremendous experience there. We were overwhelmed with all of the choices of tapas on the menu, but the waiter asked if we would trust him and he could order us some house favorites. There wasn’t a plate we didn’t enjoy and we left stuffed. We washed it all down with a bottle of Cava.
