I see Chris' point as well..
Good thing about high tops strategically placed...UD and the location of the tables determines where the crowd stands. Logistically, if they are placed where there aren't issues, some of the people flow can be controlled.
They did add counter space under the 300's and near the entrance/exit sides which pretty much replaced the counter space that surrounded the old columns in the wing area.
Other arenas have it and it doesn't seem to be an issue.
SLU has them, Bankers Fieldhouse, etc..People are going to stand around whether or not there is a place to put food.
It will be interesting to see how it all shakes out. It will be until the 3rd or 4th week of the season to determine how it all shakes out, once the regulars have checked everything out, and the people that only get to take in a few games a year get to check it out. I think the 400 level concession/restroom area is a home run for sure. If that was on both sides, that would be a huge draw for the 300/400 folks to not go downstairs.
