Skyline Chili is nothing like chili-mac. It is meat sauce and noodles, but the unique flavor hints of cinnamon, vinegar, worcestershire, and other "secret" ingredients (one of which is rumored to be chocolate or cocoa of some sort). Skyline Chili is usually served over spaghetti noodles with a HUGE mound of shredded cheddar cheese on top (called a 3-way). The addition of diced onions or kidney beans makes it a 4-way. Onions AND beans makes it a 5-way. The chili also shows up in cheese coneys, and more recently in burritos, and over fries and baked potatos. Here in Cincinnati there are many Skyline Chili "parlours" (never liked the parlour part- makes a chili joint sound like a house of ill repute) scattered throughout the city. Downtown alone, there are 4 Skylines within a 5-minute walk of each other. When the original Skyline location, opened in 1949, was closed to tear down the building in which it was housed, it was a MAJOR news story- complete "live-reports" on the nightly news (roll your eyes, but its true!). Skyline has a major competitor in another chili chain called Goldstar Chili- and Cincinnati chili lovers are often sharply divided as to which is better (this often involves blind taste-testing outside the gates at Reds and Bengals games- dont get me started on that though). Either one makes great late-night grub, esp. after a few cold ones. One last note- it seems transplants to this city usually do not take a liking to Cincinnati chili- Skyline, Goldstar, or what have you. It is nothing like Texas style chili or chili-mac. Usually those who have grown up with it, miss it when they move or go on extended hiatus- saw this just today
