Royal Host Bajikoen

Royal Host is known for having a nice classy interior with a jazzy/bossa nova background music that will remind you of the elevators of the expensive hotels or make you want to replay a Leisure Suit Larry game (I recommend Larry 6 or 7) for its soundtrack.

From the list of the big family restaurants in Japan (ファミレス), it's the clear expensive option. But don't let that stop you. In exchange they try to serve kind of premium dishes (such as including kuroge-wagyū on their menu), and the price acts as a magnificent filter to avoid weird and annoying clients during your stay, making it the perfect place to conduct interviews for your papa-katsu activities.

However I don't recommend the parking lot of this Royal Host specifically as it can be painful with a tree just in the middle, which will make you fear of people trying to get in and out with or without scratching your car 🥲
