Pete Wells gave it 2 stars, although it read like a 3 star review. He seemed to like almost everything.
"A simple red disc on a white plate, Flora Bar’s tuna tartare isn’t like any I’ve had before; it pops with toasted flax seeds and crunches with fried shallots, neither of which hides the clean, cold taste of chopped yellowfin tuna. Flora Bar does not quite reinvent tuna tartare the way Estela reinvents beef tartare, but it comes closer than you’d think was possible.
Steak comes with béarnaise and beet hunks. The beets look a little wrinkled, like prunes, and have an uncannily focused flavor. The béarnaise is silky and light on the herbs. The steak looks like steak, sliced. It is tender, and the flavor goes on and on as you chew, yet it doesn’t have the meat-locker stink of dry-aged beef. Something must have happened to make it so extraordinary, but the answer is not visible. (The beef has been given, among other treatments, a surreptitious marination in fish sauce.)"
