Chicago has its share of "roadside" restaurants. The two in the images to the left (Susie's and Murph's, at 4126 and 3930 W. Montrose Avenue, respectively) are typical. Fairly simple buildings, they are visually interesting chiefly because of their bright colors and advertising. They have "camp" value, a kind of humor.
While they look like auto-oriented businesses and, indeed, provide parking, Susie's and Murph's are pedestrian-friendly. They are small, close to the sidewalk, and provide outdoor seating. These are all features that make these shacks assets to their neighborhoods. I love these buildings.
