Got the T.O.S. Hanpan, and though we asked for it to be less spicy, it was still quite hot - so for anyone that's wondering, the chilli pepper on the menu means "Korean level of spicy". So maybe avoid that one if you're not looking for that sort of experience.
Onto the sides: Tako wasabi is raw octopus mixed with wasabi (and it smells stronger than it tastes, in this case) and comes in a small ramekin dish. Kaarage is alright, though preferred the creamy croquette that was housed in the same basket.
All in all, I'd say the meal was OK, and that the draw of the place is that the large hanpan comfortably feeds 4 adults - at $53, it's a pretty good deal. Good to try once, but not sure there's really anything special about the food itself to want to come back too many times.
