Today, October 1st, is Marugame Seimen's "Kamage Udon Day"!

Sanuki Udon chain Marugame Seimen is holding its monthly "Kamage Udon Day" event today, October 1st, a tradition on the first day of every month. For today only, all sizes of its signature "Kamage Udon" will be offered at half price.

"Kamage Udon" Regular Size for ¥190!

"Kamage Udon" is a classic Marugame Seimen menu item, served by placing freshly boiled noodles directly from the pot into a wooden tub. You can enjoy the aroma of wheat and the fluffy, chewy texture with the dipping broth. On "Kamage Udon Day," the Regular (Nami), Large (Dai), and Extra Large (Toku) sizes are all half of their usual price.
