7-11's, which I frequent often, need a slightly higher food quality selection to appease affluents like me, but as far as how they look, that's what a 7-11 looks like! It's what I look for when I'm driving, on "stroads" / highways, and am looking for an exactly predictable experience, one which is low-key, inexpensive, and does not imply a formal dress code. I'd never want a 7-11 to look like a brownstone in the west village, that would imply an entirely different kind of business establishment.
