I went to A5 (now 5A5) a few weeks ago during the soft opening and had the "A5" grade Wagyu @ $16/oz and the dry age sliced New York Steak. The wagyu was a huge disappointment, it was over salted and served with a soy sauce on the side. The meat did not cut like butter. The New York steak was much better in my opinion at $16 for 7oz.
Chef Marc came out to check on us and gave us his "special" knife still in it's tissue wrap to use. I thought it would be a Laguiole.
