We see this more and more in downtowns in affluent areas: the old central business district dominated by a plethora of restaurants. Over at Architect, Aaron Betsky has some thoughts about why this is happening:
As sprawl itself spreads, downtown areas become magnets for social activities, rather than for work, living, or shopping, and the bar or restaurant is the anchor of many such interactions. . . .
Before too long, our downtown areas, as well as those hubs of activities, from sports stadia to airports, will become food jungles, the luxuriant growth of food vending choking out any other activity at ground level, allowing the high-rises for wealthy living or white collar work to rise out of that base of bars and restaurants. . . .
