When you message them in the app, they email you back!
It typically takes 45 minutes to get your food. Shockingly, there’s a provision where you can message them within the app. But the replies come via email! No, I don’t check my email when I’m at a football game. Not part of the app per se, but in my experience you’re a whole lot better to smuggle in a hotdog or hamburger then you are to buy food at a sports venue. Perfectly happy to fit to pay 5 times the price but the quality is unbelievably bad.
