A firsthand August 2012 review of this exact 11F Wako branch says the customer had repeatedly visited since Kyoto Isetan opened in Heisei 9 (1997). This supports opening-era operation in 1997; September 11 is an estimated timeline anchor to the documented department-store opening, not an independently verified restaurant month/day. Original operator opening-day confirmation remains a research gap. The B2 takeaway counter is a separate unit. October 16, 2026 was the research date, not this restaurant opening.[1]
Kyoto Isetan’s tonkatsu venue offers a verified, dated autumn menu: Momiji seasonal set.
