I personally would suggest not going to Domo. The prices are quite high and the kitchen is inflexible when it comes to accomadations.
They also have an 18% gratuity for parties over 6, and although as a server, this is acceptable, I find it better to tip according to service quality, not based on the amount of people. *removed comment about conditions*
...
I also have a bias, since I worked there and they don't treat their employees that well, but if that is the chosen location, I wouldn't mind seeing some old co-workers.
Anyway, back on topic:
Although it's not Japanese cuisine, Chopsticks Chinese Bistro (my current working location xD) is quite literally down the street from the Marriott down on Belleview, so the commute is short. The food is pretty good (in my opinion) but again, it's not Japanese. As for other suggestions, there's a Sushi all-you-can-eat place in Aurora right off Havana, called Sushi Katsu. The price for all you can eat is around 26 and you can (as it says) eat as much as you want. It's a pretty good deal, and unlike the other all you can eat places I've been, Katsu seems to be the freshest. It too isn't far from the hotel and it's not far from my place, so I could probably carpool from dinner.
Just some suggestions. ^^:
