I had Hapa in Greenwood Village this past weekend. It was not my favorite but they have multiple locations throughout the metro. It might have just been the choice in rolls.
I honestly prefer Go Fish in Westminster. They have other locations across the metro as well.
Sushi North - Thornton
Yum Asian Fusion - Commerce City
Sushi Katsu - Aurora
Banzai Sushi - Aurora (they have an all you can eat option)
Havent tried it yet, but have a gift card for Uchi Sushi I am excited to try, but they seem a little more expensive.
None of them are super fancy. But they are solid options for suburbia. I'm sure some of the food vlogs on tiktok will have neater options.
Just saw one called Sushi Train. That looks fun! Its served on a toy train.
