I've enjoyed quite a few concerts, hockey games, graduations and even a robotics competition here. I've rarely waited more than two minutes in line before ordering a drink except during peak times. Everyone I've spoken with that works here was really friendly. The bathrooms have always been clean especially by stadium/arena standards. Some type of historical display would be nice as many artists and teams have passed through here over the years.
