Off the top of our heads....
If you're counting your macros, you can go to Protein House! So yummy.
If they have a game this weekend and you want to potentially see Taylor Swift, and experience the (I say 2nd loudest, Eric will say they're objectively the loudest) stadium in the US, you can hit up a Chief's game.
If you want to go get a badge swipe for Hannah, you can go visit the KC T-Mobile office!
