If you take the time to search out quality Japanese beef, you will not be disappointed. There are a fair number of places that sell fake Kobe Beef in the US, but there are some tips to help find the real thing.
If you come to Kansai, you’ll be able to find some of the absolute best beef you will ever have. (I didn’t believe it myself, but it is true.) This place is very reasonably priced and an amazing experience.
The site is all in Japanese, but if you can decipher it, go!!
