My fiance has moved from Chicago's northwest side, home of great Italian beef sandwiches and Natoli's on Belmont (terrific sausage you can take home and cook, or eat there on Fridays) to our home together in Lake Forest. So what he's gained in foie gras, he's lost in more pedestrian pleasures. Anyone know of some really great -- no just "okay," but great as in, worth the trip -- places for Italian beef and/or sausage sandwiches north of Lake Cook Road, between, say, Rand Road and the Lake? We're not talking "french dip" here, we're talking the real deal. Also any great butcher shops with real-deal Italian sausage to cook at home? Thanks kindly for your suggestions!
