Any place I can get a decent meatball sandwich using my meal plan in the park?

Hey everyone I’m a new season ticket holder this year and I have the meal plan. I’m just really in the mood for a meatball sandwich. Does Primo’s Pizzeria still have them? Any one location better than another? I’m seeing conflicting info on if they still have it on the menu this year or if any other place has one. Is it actually worth getting? I don’t expect anything crazy a basic meatball sub is fine I’m not too picky. Any other alternatives or recommendations are welcome I’m just trying to plan it out.

Thank you for any insights!
