I guess the people who works there don't just want to make food for the super rich. Maybe they have friends and family, and they want to imagine that the experience they create would also be available to people like that. And if that's the case then the "low" price is a fundamental requirement, and it makes sense to say that it's not sustainable (the combination of the quality and the price).

As I said in another comment, El Buli solved this decades ago by setting a chunk of reservations aside for locals from the town they were located in and another chunk only for people from Spain. Just do that and add a portion for friends and family.

I used to do consulting for a extremely high-end hotel where a single night could easily cost $3k+. Every employee got to spend a night for free every year and they got a number of friends and family discounts that were 90% off.
