Johnny O's Hot Dogs

For more than 40 years, the hot-dog doyens at Johnny O's have served up bun-hugged franks and classic American eats, including the nationally famous Mother-In-Law sandwich—a Tom Tom beef tamale nestled in a bun and smothered with chili—which earned the No. 6 rank for Most Sensational Sandwich on TLC's Best Food Ever. As a dine-in and walk-up joint, Johnny O's lets customers snuggle up with a hot dog in one of its turquoise padded booths or grab a bite to go to enjoy at their favorite quicksand pit. In addition to hot dogs, the Chicago staple doles out hearty breakfast sandwiches, cheeseburgers, and freshly fried sides.
