Most line cooks buy their beef at Costco because they don't make squat. Having worked the line and been a Chef at multiple establishments, I know this from personal experience.
I don't eat beef much, so I spend my money on the good stuff. I like about four weeks of dry age on my beef. Beef so old, it has a rind on it like old stinky cheese. Ah, but when you cut that rind off, the flavor underneath is so intense and sublime. Expect to pay between $$40-$100, depending on the age and cut, because of all the shrinkage and lose. I've also had Kobe and Wagyu many times.
IMHO, the only use for A1 is for polishing copper.
