WOW, Gary, sounds like a really great steak ...
Personally, I would remove it from the heat at 130 degrees, or maybe a little less, and let the temp rise just a bit as the steak sat for a few minutes ... But that's just a matter of taste ...
I checked out the web site - I understand that Wagyu beef is supposedly the best, and dry aged makes it even better ... but an 8oz rib eye for $41 - ($82 per pound) WOW
Glad you enjoyed those steaks ...
BTW, as I had written on these pages a while back, I have been in a program that encourages 'plant based' eating ... I'm NEVER going to be a vegan, or even a vegetarian, but we have drastically cut back on red meat ... On Christmas at our niece's I had some prime rib roast, but over the past 2 months that's been about it ... but soon we will be going to a steakhouse and there will be a nice dry aged sirloin or rib eye on my plate and I won't care what it costs ...
