The Aldi in Englewood isn't really a supermarket - it's more like a dollar-store version of Trader Joe's. They also don't sell much produce (maybe 10 feet of shelf space), and it's usually been sitting on the shelf a while. I think this is more about customer demand than availability. Chicago gets plenty of great produce through its wholesalers (and role as a freight hub) - high quality produce is abundant and cheap at the Latino markets.
