I've had A5 kobe beef at Urasawa and Cut down here in LA. The one at Urasawa was better but IMO the beef is basically just way too rich and buttery. It's like eating foie gras...it melts in your mouth and is wonderful but because of sensory overload you can only take a small amount.

I can't imagine eating like a 16 oz steak of kobe beef...so the small 4oz or 6 oz portions are fine for the table.
