Shortly after the morning rush hour, Delmonico's employees start assembling the Loop's most impressive buffet: a four-pronged monster assortment of salads, baked pastas, marinated meats, sliced fruit and international dishes including sushi rolls and pirogies.

It's a welcome option for the lunchtime crowd, particularly those who are trying to eat healthy or who like to eat a lot. The cost per pound is reasonable, but you'll be charged extra if you load up on shrimp, gourmet cheese or other "salad bar delicacies." If you're daunted by all the choices, step up to the grill for an omelet breakfast or a midday burger or sandwich.

If you work in the Loop, chances are you've unwittingly passed this place on your way to a fast-food joint or cafe. It's easy to miss. You'll have to spot its sign across from City Hall, go through the revolving door and look for the floor-to-ceiling windows. The largest crowds arrive via the pedestrian walkway between noon and 1:30 p.m., when seating for around 100 fills up quickly. Customers left standing or pressed for time can get it to go.

Average cost: <$10
