We went to the Sounds stadium for a game, so I’ll try my best to share the information I found out from them and online! There is not many GF options listed online for the stadium currently!
I personally had hummus and veggies, which came in an individually packaged container! There was also a kale salad as a GF option (it was a small salad!)
Tacos can come with corn tortillas upon request, and there’s walking tacos (confirm with them if the meat and toppings are gf). The Band Box has a GF hotdog, and for vegans/vegetarians, they have a Beyond Hot Italian sausage you could maybe ask for as GF by asking for the same bun that comes with the hotdog.
There were gluten free seltzers and wine available, Nashville Hard Cider is GF, and dip n dots (we had the rainbow flavor!)
I hope this helps and at least gives suggestions! Good luck, and enjoy the game!
