I’ve been to a handful for Michelin star rated restaurants in my life, and have really enjoyed the experience every time.
Most recently, my wife and I visited a college roommate of mine in NYC. One of the nights we went to Thomas Keller’s Per Se and did the 9 course tasting menu. Just to make reservations I had to put down an $800 deposit (200/person), and I believe the bill was around $450/person without tip.
My buddy and I ended up splitting the bill, and it was north of $1300 per couple but it was well worth it. Once in a lifetime experience. No single ingredient was used twice during the meal. I thought that was kind of cool.
