Even though I'm not Chambo, I'll give my thoughts anyway.
I'd be interested in Chambo's thoughts as to why New York has not embraced this restaurant.
New restaurants have a VERY narrow time window during which they have the chance to attract good press. Lincoln had its chance, and most of the early reviews were not favorable. The press moved on, as they always do.
If Lincoln had been a stand-alone restaurant, I suspect it would have closed already, not because it deserved to, but because it had misssed its opportunity. Fortunately (for them), Lincoln Center supplies a captive audience; meanwhile, Benno keeps improving the place.
I was one of those who was not impressed with Lincoln v1.0, but because I'm a Lincoln Center regular, I kept dropping in, and saw it get better. (I realize there are some who thought it was excellent to begin with; I'm just giving a personal perspective.)
But there isn't any forcing event that would bring back the press, and Lincoln isn't in a part of town where the food cognoscenti tend to just "drop in". So Lincoln's excellence is destined, for now, to remain our little secret. Most people don't expect a restaurant attached to a performing arts center to be anything more than just adequate. There's nothing that would cause people to say, "I must go to Lincoln," unless they're at Lincoln Center for other reasons.
