Japanese Beef; Wagyu and or Kobe

The recent post by Maki about Fugu got me thinking about the other really expensive Japanese restaurant meal. Kobe beef. So who here has had this delicacy and what did you think of it? Was it home cooked or restaurant. Is it really worth the cost? I was thinking about it also because my husband and I went to a very fancy restaurant here for our anniversary, which is one of the few outside of San Fransisco to serve this beef. It's called Alexander's steak house and is a asia/western fusion place with a big emphasis on beef.
