I was just in Chicago and had a fabulous corned beef sandwich at a little place right around the corner from HotHouse (31 E. Balbo 60605-2121). It's a few doors in from the southwest corner of Wabash and E. Balbo (two blocks south of W. Congress Parkway). It's called something like A&J Sandwiches. Could any Chicagoans reading this please fill in name and address for me? Loved the sandwich.
