Grocery shopping is not just a quick trip to one store anymore.
Growing up in Chicago, my mom would “let” me do the grocery shopping. Depending on where we were living… this was a trip to the local Jewel, A&P or Potash Brothers. I loved shopping then, and I still love grocery shopping now.
However, the shopping has gotten more complicated because none of the stores are good at everything.
I regularly shop at Caputo’s, Casey’s, Costco, Dominicks, Jewel, Michaels Fresh Market, Sam’s Club, Trader Joe’s, World Market and Whole Foods.
Michaels and Caputo’s have great produce sections. Large open areas and bins piled high with fresh produce at great prices. These two stores also have great, reasonably priced deli counters. A pound of meat might cost 1/2 what it costs at the big name supermarkets. But Caputo’s (111th and rt59) is special.. the deli looms large, premade dishes and an extensive selection are just the tip of the iceberg at this place. As 
much as I love Michaels (next to Sam’s at rt 59 and Ogden) I would have to rate Caputo’s as a Naperville business that you need to know… also the best fresh bread department in town… Yum!
For your staples: cereal, milk, soda etc… Jewel, Dominicks and Meijer are the places to go and while they are pleasant places to shop, they are missing the boat in produce, meat and deli. Dominick’s has a very good web site where you attach coupons to your phone number (or card) so that you don’t have to worry about forgetting them.
If you like meat or quality prepared foods try Casey’s Food Market at Gartner and Washington (right by Trader Joe’s.. yum!) Casey’s always has a staff of butchers working, these guy’s know what they are doing… it’s pricey, so I save it for special occasions (love their heart of rib eye steaks – like Filet Mignon except with texture, flavor and richness)
Whole Foods is conveniently located in the same mall as World Market (the BEST place to buy coffee) just across the street from Costco, this is like the one-two-three punch of greatness… the only problem is deciding where to go first….
