SF is a pricy place to live in, but here’s a picture of their menu - I wouldnt pay $57/person for four courses (and you know they werent large portions) in 2019. and that was before food prices went crazy - 2019 was the last year their restaurant was open. my bet is that the restaurant had financial issues.
unless they can grow the things that arent in season - you know, the stuff that people are used to eating when they’re eating out, then cancelling out CO2 emissions means nothing, food imports from other countries will continue apace. if all you can get at an upscale restaurant is in-season ingredients then you can just cook at home for half the price.
