I have had kobe a few times. It is distinct from wagyu, because that only refers to the breed of cattle, of which much that is labeled wagyu is interbred with more typical American beef cattle, but can somehow still be called wagyu, and in many cases, inaccurately labeled kobe.
My most memorable experience with Kobe was paying $30/Oz getting 5 ounces of thin sliced raw Kobe and cooking it on 700 degree hot stone for a second per side and then having the option to dip it in various oils and seasonings. Of course it was enjoyed with nothing, maybe a few grains of course salt.
It is truly a remarkable beef. The price makes you appreciate it all the more. But even if it had closer price parity with more traditional cows, there is no question as to its sensory superiority.
