The Two Guys chain of New Jersey operated stores along the Eastern Seaboard and in Illinois and California. Above is a rendering of the Burlington County (Marlton), New Jersey store, which opened in 1973.

Here we have a physical layout of a mid-century discount mart; in fact, the same one depicted in the exterior rendering above. Two Guys locations were quite huge and included a supermarket, auto center and "Snacketeria" restaurant.
