Cava San Miguel is a wonderful area just off the Plaza Mayor, in Madrid. Mesons are like Hobbit Inns, but for the square door. Very homey, very good food generally, but this can be said of a lot of places around Plaza Mayor. It was closed at this early hour, which was fine by me, as I loved the red door in the wall. Spaniards will use any excuse to add a dash of nature to their environment. Medieval fortifications are no match for Spanish vines artfully put there by a Meson’s owner.
