I have a somewhat out of the way place for most of you, but it's a favorite of mine and my friends - The Lantern in Lake Forest. It's very much a locals pub and restaurant, with great service all the time, in a warm environment with a good amount of Christmas decor and lights plus model railroad trains running overhead. They are famous for their burgers which are excellent. In fact, I'd go there over Charlie Beinlich's if given the choice. It's right next to the Lake Forest Metra station for those in the city or North Shore.
