There are lots of shops named 'Soba-ya' (Soba shop) nationwide where both Udon noodles and Soba are listed on the menu, however in the Kinki region, such shops are named 'Udon-ya' (Udon noodles shop) because customers order Udon noodles more frequently than Soba.
また日本全国にうどんとそばの両方を供する「そば屋」と称する店が多いが、近畿ではうどんを注文する客のほうが多いため「うどん屋」と呼ぶことが多い。
