Last time I was there they did it by weight
They go by sizes. S 4.5 M 5.5 L 6.5 They have never been self serve, but each size corresponds to a certain amount of yogurt.
If I remember we paid by scoop or cup size about 2 months ago and the toppings were fair price for 2. It was a better price than other places we've been.
It varied by what you want and toppings and size.
