I would try it and then keep eating rib eyes from Publix. No matter how good it is, I would feel stupid spending that kind of money on meat regularly. A good choice rib eye fried in butter is a truly amazing piece of meat. Better than prime from Ruth's Chris or Smith & Wollensky because of the superior method of preparation. Yeah, I said it. Rib eyes go on sale here for $7 per pound.
If you ask me, people think too much about super-luxury ingredients and not nearly enough about how to cook. Anyone who can't make a $10 dinner that will make people groan with pleasure is a hack in the kitchen, and great ingredients can't fix that. All the Wagyu on Earth can't compensate for lack of talent and effort. I guarantee you, thousands of people cooked and ate mediocre Wagyu steaks tonight and said they were magnificent because they didn't know any better.
I've had some high-end grub in my time, but the best food I ever ate came from my own kitchen, and most of it was cheap. The other day I slapped together some creme brulee that was beyond belief, and the food cost was under $5. No restaurant could beat it. I make Sicilian pizzas I like better than any pizza I've ever paid for, and I lived in New York. Runs maybe $5 for a pie too big for me to eat responsibly. I've never had cheesecake anywhere near as good as mine, including the remarkably overrated Junior's. To me, cheesecake is the second-best food there is, and it's cheap compared to steak.
A really good macaroni and cheese is really something. The stuff they sell in restaurants is garbage in comparison. I'd rather have really good macaroni and cheese than an unimpressive meal with a $300 food cost.
It would be nice to find a piece of real Wagyu, cooked by someone trustworthy, just to see what it was like. I'd also like to try some really good caviar some day. I wonder if there is such a thing as a Wagyu rib roast.
