R J Grunt's - Chicago
Rich Melman and Jerry Orzoff launched the Lettuce Entertain You empire with this restaurant, back in 1971. Designed to feed hippies with the munchies, R.J. Grunts still offers plenty of appealing chow, from the all-you-can-eat salad bar — Grunts introduced the salad bar to Chicago — to chili, burgers, malts and more.
