Slinking into one of the custom booths at this cheerful diner is worth the long wait – you’ll dig into the best traditional breakfast in the South Loop. The omelets include lots of healthy options (the Iron Man is made from egg whites and comes loaded with veggies and avocado), and sweets lovers have stacks of cinnamon-roll French toast and peach-cobbler crepes to drench in syrup. Scores of big salads and burgers are on hand for those inclined to order lunch.
