Re : Kobe Beef dinner
Here's a restaurant I'd highly recommend. It's located minutes from Sannomiya station and it's a place my friend (who's spent her whole life in Kobe) took me to last November. The only problem is that I'm not sure if they have any English speaking staff.

At the very least, you'll get a good idea of the prices by looking at the menu above.
