there would be no Chipotle if the housing prices kept going up.
Or if there was, it would be a tourist stop and would certainly make its money on volume. Basically, it would be like that god awful McDonald's on the Champs Elysee.
In any case, the price for it's burritos would, in all likelihood, not rise to an unaffordable number. At the same time, local residents would not make up the bulk of its customers.
I don't follow this at all. Are you suggesting that restaurants would simply disappear from SF entirely? Or that locals would never go to restaurants? It seems much more likely that restaurants would just get more expensive during which time there would be some churn and turnover in the market.
It makes me cringe that one would even think of Chipotle as an acceptable place to eat in fucking San Francisco.
