without realizing it, MC invited Houjou to travel with him someday (unconsciously intending for her to become his wife for future). very smoothly move and on the last page, i'm sure he's Houjou older brother
When I Googled it I found it's also a Japanese Yakiniku BBQ chain in Tokyo, California and Texas as well as what looks to be an unrelated small restaurant in Berkeley, CA. (I don't know how the hole-in-the-wall restaurant avoids trademark issues.)
Slight additional research on the former:
Why it's seen as "Upscale Casual"
Premium Ingredients: They serve high-quality cuts including U.S. Prime, American Wagyu (Kobe-style), and sometimes A5 Miyazaki Wagyu. Their signature "Tokyo Negi" beef tongue is a standout that differentiates them from basic BBQ spots.
Price Point: While you can have a "reasonable" meal for around $50–$70 per person, a full experience with premium Wagyu and drinks can easily climb to $100+ per person.
Atmosphere: The locations (such as those in West LA, Costa Mesa, and Tokyo) feature modern, sleek interiors and attentive service, making them popular for dates and special occasions without being overly stuffy.
