Are you sure you went to Ghiradelli's?

They have a lot more choices than that. It sounds like you ordered the wrong thing-a single scoop strawberry sundae, which is not the best deal.
At Ghiradelli, it's all about the chocolate! 
They are a chocolate company, so that is their specialty. They have three different types of hot fudge, not to mention the other traditional toppings. For about a buck more, you could have had one of their two scoop specialty sundaes. I highly recommend the butterscotch hot fudge sundae with dark hot fudge.
