Update: These new treats are apparently in a testing phase and may not be on the menu for awhile.
Flavors include strawberry, blue raspberry, pina colada, mango, and passion fruit, then condensed milk is added on top. This new offering is $4, but is not currently on the menu, so guests will have to ask for it. Because it is still in a testing phase, it may not be readily available.
