Cold Stone in Phoenix in the summer? Great! This location? BUSY and slow but it is the summer. On our last trip we ordered a malt and were given a normal ice cream. When we asked for the malt, the server said they don't have malts. We asked for a shake and it was prepared. It seems to me that you should not make assumptions and when you do... the obvious guess is that we wanted a shake.
Either way, it was tasty (if a touch expensive. Local yogurt places are about 1/2 - 2/3 the price of Coldstone's prices nowadays) but due to the location and time of year it took 30-45 minutes to get through. If you have a craving and don't feel like sitting in line, this may not be the best location.
