[1] The mall houses more than 60 shops, over fifteen restaurants (including a Davidson's Bar and Grille,) a ten screen 2,300 seat Cineworld cinema (the largest in Aberdeen) and a 3-star Leonardo hotel with 203 rooms.

In January 2024, Marks & Spencer announced that the Union Square store will be extended, absorbing the neighbouring TK Maxx, with the expanded store opening in 2025 following the Bon Accord Centre branch closing.

The shopping centre is now part of a covered interchange between the bus and railway station.

Additional bus services run past the centre via Guild Street.
