They actually sell Prime Steaks at Costco at 1/2 the price of Citarella and they are delicious.

Why dog food? Because I would not consider serving a "select" cut to humans unless they seriously want to loosen some molars. A puppy on the other hand can have fun with it for days.

Thanks, pierino and thirschfeld, for educating me once again. I read the link I posted on the fly. Did I actually read it wrong? I have never seen select. Why dog food only?

prime, choice and select

Good luck on finding "prime" unless you have a real butcher who wrangles primal cuts. Most of it goes to restaurants, and "select" goes to dog food. Or at least it should.

Sorry, to clarify -- select isn't the lowest grade period, it's just lower than choice, which just means it has a bit less marbling. This post clarifies the differences really well: http://bit.ly/Ui6mJ

Actually select is the lowest grade, pointed out by @KCBeerman on Twitter.

Prime first, select second, choice third.
