@evan thanks for the insightful thread. I want to push back on this assumption:
> if you make the dish at home, you are somewhat or even very much less likely to go buy it at the restaurant
This assumption seems to treat going to a restaurant as strictly transactional. But in practice, I don't think people go to a specific restaurant just to buy a specific dish. It's a mix of the food, ambience, not wanting to cook, etc.
