In June we had a milkshake at Sci-Fi and Whispering Canyon Cafe, and I had a malt at Prime Time. The vanilla shake at Sci-Fi was definetly the best!! The malt from Prime Time actually made me sick. I have heard lots of people say the PB&J shake is really good. To me it didn't sound very appealing, but I may have to try one if we ever go back. The WCC one was good but I think the one at Sci-Fi was better!!
