This is a fairly common bento in Japan and most places would serve it room temperature or lukewarm in a single layer flat bento box.
But this chef was not satisfied with that. Oh no.
Followed by the top of the top enclosure, which sealed both it and the outer container, with two tabs (one for popping the top container off the bottom and one for opening).
Bold, but plausible.
About $20 (plus whatever Uber charges/you contribute to restaurant/driver) so a premium on a Tokyo lunch, but very very worth every yen.
This just wasn’t the delivery experience for a restaurant meal.
