I've said it before, and I'll say it again - self-service frozen yogurt is genius! gone are the days of paying for more than I want/need, and then eating the surplus out of guilt/lack of self control (usually the latter). I choose which flavors I want, how much of each flavor and can then load up on as many toppings as will fit in my cup! And the beauty is that you pay by the ounce ($0.30 an ounce I believe).
So far, my favorite flavor is the tart. But you've got to love the seasonal flavors and the creativity involved in the naming process.
However, if I could change one thing about my beloved Yogurtland (and there's only one thing I would change- with the exception of receiving special designation that would entitle me to free Yogurtland for life), it would be to encourage recycling. They hand out adorably colored plastic spoons with each cup, but there's no where to recycle. Environmental-friendliness is always a plus in my book!
