We eventually arrived in one square that was edged by bars and eateries. We wandered up to the menus on display to see whether a: they did the Cava and b: how much. To Martha’s shock, one place quoted 30 euros for a jug. She scoffed at this, understanding that if you had such good Cava, you would never put into a sangria mix, by this time, however, we were desparate, so ordered the normal red wine sangria. The Cava would have to wait. Once we were sated and entertained, we returned to our hostel to get some shut-eye.
