The cafeteria/bar San Miguel in Plaza de las Monjas (next to the colegio San Miguel just off avenida Castilla Perez) is a very popular place, particularly during the day. The interior is relatively small but it does have a very good-sized terrace.
I had ‘carne con champiñones en salsa’ – meat with mushrooms in a sauce – which was served with fresh from the frier chips. The meat was tender and the salsa was rather tasty. A beer and a tapa, €1.90.
