Staff is always really nice and will let you try any flavor to be sure you get what you want. They have Groupons regularly that are $5 for 2 medium cups of ice cream - which a great deal, since that would run you about $10 if you purchased it the old fashion way.
The plain chocolate is to die for and the fact that it's better for you than ice cream is just a bonus on a hot Phoenix day!
Overall: A+
