Thank you for the update!
Note: I believe the ramen shop featured in this chapter is the original Harupin Ramen in Suwa, Nagano (the Suwa flagship store, specifically), rather than Harupin Miso Ramen Raizo (which is a spin-off concept focused on miso ramen).
I also think the Tenhou location featured in this chapter is the Suwa Inter store, which recently moved locations and changed its name to the Suwa Station Park store.
