I think the most important thing would have to be to have a very nice hotel for the away teams. With that comes with a very nice restaurant and a very fancy lounge area to have a drink around.
Then with that, I think a club and a bar that is happening would have to be very fun. Imagine if you play a game and win a game and right near the arena there’s a good night club. So you can have your stuff at the arena and then walk over and boom, you have a nice place to party and a safe place to party where people in the city know to go and celebrate with professional athletes.
Other than that, I think having places like sports restaurants to watch the game and to have an ambiance to travel to the arena. Like in Toronto ti watch the game in the downtown of the city of the sports teams.
