This is way nicer than any other arena I have been to. I find it to be nice, clean, and well lit. Lighting becomes important as you get older :). It's always a plus when I can see. In addition, there is the largest scoreboard I have ever seen. I have no problem seeing it.
Dining options are plenty. They have traditional "arena" food. Pizza, pretzels, beer, chicken tenders, and fries. However, there are more high end options as well. Michael Symon has a burger place here. I think I even saw a sushi place while walking around.
The bathroom situation is better here than at most public arenas. They seem to be everywhere and are plentiful. I have not noticed the dreaded line out the door for any ladies room. That's a good thing.
I'm glad Cleveland is having its moment. This is another example of something exemplary in Cleveland!
