I live about a mile from the middle of downtown in a mid-sized US city, in what is ostensibly one of that city's most walkable neighborhoods. I don't think there's a single mom and pop store within comfortable walking distance, the closest grocery store is about 3/4 mile away (though there's also a farmer's market about 3/4 mile away in the other direction), closest barbershop is about a mile away, etc. Lots of restaurants, bars, and breweries nearby though.
