I agree to a point about N/naka, though I don't think it was just NBC Olympics-esque fluff. I found her whole story low key interesting but it squeezed out time for other things I'd have liked to see.
I wish they could've walked through the whole customized menu system for each customer. Keeping notes on likes/dislikes on customers is one thing, but creating a unique serving each night for each guest (to what extent??) seems unmanageable, would've been nice to see how far they actually pushed the system.
