At the other end of your search, in the south end of Hartford, is Costa del Sol, a wonderful traditional Spanish restaurant on 901 Wethersfield Ave, about 1 mile from the Airport Rd exit of I-91 (Exit 27, left on Brainard Rd., left on Airport Rd., go 1/2 mile then left on Wethersfield Ave., 1/2 mile on right). http://www.costadelsolrestaurant.net
