Ours (and the only other one I've seen is a classic "cattle crush". when walking towards the building, it's brick, no windows except for the exit end. You enter on the second door from the end, and make a sharp left. You cannot exit that door, but must at least complete most of the circuit.
The left wall is lined with pallets of cut/tear open boxes, and there's three "lanes" (6 product faces/facets). Facet 1 is the first lane you enter. It has biscuits, sweets, crisps breakfast cereals soft drinks and cordials. End wall is cosmetic/hair care. Centre has some electronic stuff, and their "special" chairs/tents/PCs etc. Next across is the fruit/veg and frozen food.
Very last lane is the meat dairy and bread.
Then you head towards the light, and are "greated" with the only Aldi employee in the store, a large, middle aged lady with a scowl.
It's a very clever layout from a psychological point of view. No distractions, just get the job done filling up the cart, starting with the rubbish optional stuff, then the stuff that you stopped in to look at, and finally the stuff that you really came to get (food)...then escape into the light.
I've got a couple of similar layouts in my yard, and they are quite effective.
