At Mos Burger, the special menu "Mountain Potato", which has the image of a snowy mountain, is available only in the area. It will be available at all 26 stores in Nagano prefecture on Friday, Saturday and Sunday for a total of 9 days from February 12th to 28th, in line with "Snowy Day" in Nagano Prefecture.

Shinshu (Nagano Prefecture) is an area with a lot of snow. As an opportunity to consider snow as a blessing of nature that supports living and ecosystems and to think about its value and meaning, the "Snow Resort Shinshu" promotion committee made by people involved in ski promotion in the prefecture will start "Snow" on the 4th Sunday of February 2017. It was enacted on "Day of the Day". February 28th is applicable for 2021.


This time, if you purchase "French fries S", "Potato S set", and "Moss waiwai set" on a snowy day, you will receive mountain potatoes with about 1.5 times the amount of French fries S. The idea is that you can feel the same joy as the excitement of snow at Mos Burger stores. Please note that various variety packs and UberEats menus are not supported.
