The restaurants are there and successful because of the density, though. The falafel shop around the corner from three multi-storey office buildings can't afford to have a location in every suburb that formerly sent workers to the business district.
There's existing evidence for this: how many restaurants do you see in standalone office parks? A few perhaps, but nothing like what's downtown.
