Also, Save-a-Lot has a very weird but effective layout. Literally every one I've ever been to has forced you to walk through the rightmost aisle to get to the rest of the store. I find it strange that, with Save-a-Lot being a known moocher of former buildings, they at least design the interiors consistently.
Finally, there's the Kroger in Grand Blanc, Michigan. According to my mother, this store (an anchor to a very small mall) in the early 70s. It seems to have been expanded in the greenhouse era and then sold to Kessel Foods, which bought a bunch of Krogers (and later, a couple Giantways), only to revert to Kroger just like almost every other Kessel in the late 90s-early 2000s. It's sort of a corner entrance; the main entry leads you right down the main entryway, with all the other aisles on your left. I have no idea where the entry was when it was still anchored to the mall, but I would guess a left entrance off the mall concourse.
It looks like the store took out part of the mall to expand, gobbling up an Ace Hardware and a drugstore. I think they might have torn down part of the mall to do this, as the Kroger's roof is higher than the rest of the mall. Here's what it looks like now: http://www.bing.com/maps/default.aspx?v ... &encType=1
Here're pics of the three layouts of which I speak:
