Yeah the new (“improved”?) bathrooms were small and all had crazy lines pregame, both upper and lower level.
the west side upper deck is great. The open terrace area where you get off the escalators was nice. the walk through market/concession stand on the 50 yard line is great. Large with plenty of self checkout stations. They need 1 of those on each level on all 4 sides of the stadium. (The one on the lower level is poorly placed and just caused more bottlenecks.)
Other than looking more modern, the lower level was meh/worthless.
nothing was done to ease the congestion in the north end zone. The only place to get water on the north end lower level was the same single set of concessions stands with a 15-20 minute line before kickoff. Tons of vendors carrying tubs of beer but none had water. (Haven’t been to the east side in years, so no comment)
the money was clearly spent to add the club /suites in the southwest corner which only benefits the ~200 BMDs and their family/guests for each school (water is wet).
