I live in a suburban neighborhood. We're near a number of stores and restaurants without crossing any streets, and the number multiplies if you allow a crossing or two. An actual grocery store is about half an hour's walk, but it's closer than the freeway, and you'd pass three or four convenience stores and about a dozen restaurants within the same distance.

Getting to Mega-lo-mart would be a 45 minute walk, and involves going under the toll road overpass and crossing about 4 streets (so, a little farther than I'll want my kid going anytime soon).
