Why is the Jewel at 53rd and Pulaski popularly referred to as the Grand Bazaar?

I think Jewel built several "Jewel Grand Bazaar" supermarkets in the early 1970s that were larger than other Jewel supermarkets at the time; these may have been the first ones to include drugstore-type merchandise. Others were built in Franklin Park (the prototype, I think) and at 87th/Dan Ryan.
