Until very recently, you would have said that a $150+ tasting menu is something that only a few places can get away with. The old guard has to be now wondering how high it can go.
One big difference is that you can still dine at Jean Georges for $105. Counting amuses, you'll still be getting about 7 courses, even though it's not technically a tasting menu. The food is the same quality, and you've got a lot more flexibility about what to eat.
If you want Atera at all, the no-choices tasting menu is your only option.
Yes, it has been a dramatic change. Most of the old guard offer lower entry prices (not Per Se, obviously). Brooklyn Fare, Blanca, Atera, Ko - no. (Of course, there are economic reasons for this...)
But it has to be good, as the failure of Romera shows.
If you insert Romera in the list, its real problem is highlighted. Along with Per Se, it becomes an obvious outlier (at its opening price, anyway).
