I've been here twice for group Christmas parties. The nice thing about this venue for a work function is that you can chat with folks for a bit, then everyone's focused on the stage for the rest of the night, and if people want to hang out afterwards you can go downstairs to the casino.
The main acts have been good both times, and the opening game act was really good the second time. The tables are often identified by the opening act, and there's a mix of work groups usually there like a furniture manufacturer or a paper distribution company. The food is just okay, your standard turkey and fixings, with squares for dessert. Good seasonally inspired drinks are on offer as well as the standards. A fine choice for a small company function.
