Shioya Umeda is a stand up Udon/Soba restaurant known to be the birthplace of “Korokke Soba” or a Croquette in buckwheat noodles.
You can find Shioya in the underground maze of restaurants near Hankyu Umeda. At the bottom of the escalator from Hankyu look for McDonalds, then enter the underground maze.
This place is standing only, so the flow of customers is fast. The noodles are extremely cheap, about 350yen for the Croquette noodle set in the video.
