On the contrary, to me it would be a net positive if a restaurant was going to advertise their sources. I for one am highly skeptical of the perverse incentive between restaurantees and restauranteurs—restauranteurs being incentivized to buy the cheapest ingredients possible to minimize cost. That doesn’t align with my goal as a consumer to nourish myself with the best quality food. If the restaurant can assure me they only use organic/high quality ingredients that gives me some peace of mind and is a +1 in my book.

And this isn’t just fearmongering. For most restaurants it is uneconomical to cook with anything but the cheapest vegetable oils which are guaranteed to oxidate/become carcinogenic at the temperatures required to cook the food they’re serving. So if you eat out often, being informed about a restaurants sourcing and cooking habits is definitely worth knowing about.
