I picked up a flyer for next week's sales after shopping at the West L.A. Mitsuwa. Next weekend (specifically the 8th thru 11th) they're celebrating Mitsuwa's/Yaohan's 15-year anniversary there, and they're also having a grand opening for their remodeled bookstore, which will apparently include a cafe now. As part of the celebration, Santouka will be offering kimchi ramen.
Part of the flyer (including the Santouka mention) is here:
I'm curious what is written in the Santouka part of the flyer next to the number 30 in the yellow oval. Hopefully it's readable.
