Would love to see Chobani offered in more flavors versus the non-Greek variety currently offered in your Takeaway cooler. Greek yogurt has much more protein and is more filling. (Sheetz currently offers drinkable Chobani yogurt but I would prefer a tub I can eat with a spoon.)
It would be nice to have more nutritious and healthy options for milkshakes. With the exception of the few smoothie choices given, all of the ice cream has an extremely unhealthy and high fat content. I would be much more inclined to buy a milkshake for myself or my family if better choices were available. Now, I avoid them like the plague...too much fat! Greek yogurt is more nutritious and has protein.
Gyro. Pita bread, lettuce, tomato, tzatziki, and that lamb & beef stuff. You could put fries in it and substitute pita for sub roll to make it like a gyro po boy. You could sub out gyro for chicken or the Philly steak.
