Had the tasting menu at Blacbird (1*, Chicago) and The Musket Room (1*, NYC) recently. Both phenomenal, I wouldn't bat an eye if Blackbird were upgraded to 2 stars. I feel they are right on the cusp. The Musket Room was lovely, in particular the 50 day dry-aged beef was one of the best preparations I've had.
I'm finally dining at Chef's Table at Brooklyn Fare this week. I'll report back.
