How does the Olive Garden never ending stuffed pasta work? When you pay extra for a topping, is that topping unlimited too?

I understand that the pasta and sauce combinations can change without additional cost, but after you pay the extra 5 or 6 bucks for shrimp, can you get that on all future dishes, or is it a one time thing and you would have to pay again to get more?


if you look on their website, you will see all that you are asking about
