Or they could do this:
The Salt Lake Walmart is within a 3- minute walk of a light rail station, but they basically just used the same crappy suburban store concept with a parking garage attached to the front and a cart escalator inside. It faces into the block away from the street and if you're walking there (as many do) you actually have to walk through the parking garage to get to the store.
That's the store entrance. Doesn't it look welcoming?
I realize that Salt Lake is worlds apart from the other cities with urban concept stores that we've been discussing, but it can't get much worse than this.
