Denin Prime is one of the larger asteroid colonies on the Belt. As a result it has become a sort of hub for trade and culture.
Of particular interest there is a government center for the Belt. It’s one of the main locations for managing identification money and business.
Also there is a popular local venue called the Cat Call. It’s the place to be if you are visiting the Belt. Admission and food is pricey but it’s a good venue for seeing popular galactic acts due to ticket availability and the relatively small venue. They have also taken pride in their appearance and service. It might not be blue blood enough for a Venusian banker, but for most other galaxy denizens you’ll find an evening of refinement.
