I do remember Herry posted that his favorite restaurant in Japan was Misogui-gawa, a French restuarant in Kyoto. He also listed it as one of his seven favorite restaurants in the world. So, I would think that's a must visit while in Kyoto.
Have you ever seen the "Anthony Bourdain: No Reservations" episode where he visits Osaka?
Well, ever since I watched that episode I have wanted to try the sushi place that he goes to in Osaka and swears was the best sushi he's ever had. It's a teeny-tiny hole-in-the-wall restaurant near Umeda Station that's supposed to serve the most amazing sushi. It's been run by the same husband and wife for the past 40-something years. And if you see the episode you'll practically want to make a trip to Osaka just to taste it. I was able to figure out the name and location of the place after doing a little digging:
Abeam: Thanks so much. This is great. I'll be sure to check it out.
My fave sushi place in Osaka is Endo Sushi, next to the wholesale market. I wrote about it here a while back. Also, if you want an amazing but expensive gastronomic feast (at a restaurant Tetsuya Wakuda said was his favourite in Japan), check out Kahala on your next trip. I also write about it here.
