What should I eat on my last day in Tokyo?

Tomorrow is my last day in Tokyo… what should I absolutely not leave town without eating?

So far I’ve had:

* Okonomiyaki
* Curry
* conveyer belt sushi
* Soba
* udon (I actually ordered ramen but they brought me udon instead 🤷🏻‍♂️
* Karaage
* Monjayaki

Note: I’m headed to Osaka next, so just looking for stuff I can only get in Tokyo (or stuff that’s better in Tokyo). Sweets/dessert recommendations also welcome! My hotel is by the Ueno station, and I’m planning on hanging around Asakusa and surrounding areas tomorrow, so ideally looking for something in this area.

Thank you!
