Haro is the wine capital of La Rioja. Its Casco Viejo (Old Quarter) and best taverns are concentrated along the loop known as La Herradura (the Horseshoe), with the Santo Tomás church at the apex of its curve and Calle San Martín and Calle Santo Tomás leading down to the upper left-hand (northeast) corner of Plaza de la Paz. Up the left side of the horseshoe, Bar La Esquina is the first of many tapas bars. Bar Los Caños,
behind a stone archway at San Martín 5, is built into the vaults and arches of the former church of San Martín and serves excellent local crianzas and reservas and a memorable pintxo of quail egg, anchovy, hot pepper, and olive.
