How much do you think people spend here per person? Is there combo for a certain amount of people, like $120/ 6 people?

Their menu is online. Entrees are $10 to $17. I would say their entrees are plenty to feel full. If you order appetizers, sushi, or drinks it will be more. I'm not aware of any combo for larger groups.

There are definitely combos, I know they have one for two that's about $50. I have been here several times and generally pay about $50-$60, for two. On Thursdays you get to add a BBQ dish feed when you order 2, so if you went on that night you could get two meals for free. Great place and highly recommend it
