After I was done shopping there the other day, I got myself a cup of Costco's soft serve frozen yogurt. While they offer chocolate, vanilla and swirl, the choice for me was an easy one and I got the chocolate.
chart of the nutritional value of some of Costco's food court items. Even just looking at it, it is impressive. I put my membership card in the photo so you could get some idea of how big it is. Finally, at $1.35 (plus tax) it is another one of their items that is a great value. At that price you can justify taking the family out to the food court just for the frozen yogurt as a treat.
