In this day and age, Old Chicago locations are common enough across the country that many diners have forgotten this chain's humble beginnings: It got its start not in Chicago -- or anywhere else in Illinois, for that matter -- but in Boulder, in 1976. Old Chicago is part of the Rock Bottom line of restaurants, and beer features heavily on the menu; the bar has 110 kinds available at any given time. The pizza is another draw, served Chicago-style, original or thin crust, with signature toppings and build-your-own options. The rest of the menu is about what you'd expect from a pizza-heavy, beer-centric venue: burgers, pasta, calzones, starters and salads. But for dessert, you can't miss with the renowned Big Cookie.
