I think it's quite likely that midprice, full-service restaurants are an inefficient use of expensive urban space. It's also possible that they're an inefficient use of valuable urban space, and would be squeezed out of dense cities even by healthy, responsive real estate markets.
That second claim is much bolder, though, and my personal guess is that taller buildings and better mass transit would relax labor costs via lower rent, while also lowering the price of downtown real estate. A few extremely dense cities (NYC, Tokyo, whatever) might use better transit for a "reverse commute" where people live near work and go outbound for restaurants, but that's even more hypothetical. And I can't really think of a "free real estate market" city to use as a reference, because I'm not sure anything close exists at this point.
That would assume that the real estate market is a free market, which in many cities is a laughable idea.
