I've eaten Kobe beef in Tokyo and dry-aged porterhouse steaks in the best of the US steakhouses. Sure, I can cook up a steak at home that will be better than most steakhouses (as we all can), but every now and then I like to splurge. I think I deserve it!
As for price, I don't know where jig's eating, but you can spend almost half that for a prime, dry-aged porterhouse at Peter Luger in NYC that feeds two. Peter Luger, btw, is arguable the best steak house in the US.
You can go to chains like Ruth's Chris and get a mediocre steak at an over inflated price. But you get what you deserve when you go to a chain.
