Jewel was one of the early proponents of the "store within a store" concept. Starting around 1960, they implemented this new form of departmentalized shopping in all of their new stores and retrofitted the concept in their existing higher volume stores. The departments all had a theme designed to convey the feel of an individual storefront.
The initial "stores within stores" were "Jewel Pastries" (frozen cakes and other baked goods) the "Sausage Shop" (deli meats) and the "Patio Food Shop" (pre-prepared foods including potato salad, barbeque, fried chicken, etc.), along with traditional standard departments - dairy, produce, meats and the like. Later on came "Pier 14" (seafood). The Patio Food Shop was later renamed "Chef's Kitchen".
These photos are from the Oakbrook, Illinois Jewel, which was located next to the famous Oakbrook Center Mall and featured an exterior design by the same architect as the mall. They were taken in 1962, shortly after the store's opening. This was a special store designed for an upscale clientele and featured the chain's first liquor department. Pictured here are several of the "stores within a store" along with the main entrance.
