I've seen a few mentions of Yamada on here, but nothing in depth. From what I can tell, they are open until midnight. If I am correct in that, do they require reservations? Will they seat just one?
I am hoping to fit it in either after my meal at Koju (res at 18:30), after DEN (res at 18:00) or perhaps before Ryugin (res at 21:30). Does that sound doable?
