My thoughts on the concourse layout:
If you’re in the upper bowl or in the lower bowl sections 118-104, your food options are… terrible. I’m kind of suprised they didn’t make a small tunnel to connect the two ends of the street level concourse. It must suck if you’re at the end of it and having to haul all the way around to get something you like.
It looks like there are ton of washrooms, but how big they can’t be judged based on the map.
I imagine the upper concourse (old main concourse) is a bit less crowded, but I imagine lots of people will stroll to the other concourse for eats.
I’m also shocked how a majority of the “premium” spaces are on the upper bowl, where the cheap seats tend to be (except for the suite entrances).
