Mango Tapioca Smoothie from Rainbow Cafe. Treat yourself with layered goodness of creamy vanilla tapioca, tangy fresh mango, and sweet vanilla ice cream.
This item is not on their regular menu, so just ask for the mango ice cream special. Or point to the sign on the wall (see picture below). Rainbow Cafe is located on Beach Street (cross sectioned with Oxford?) in Chinatown, Boston. I'll see you there!
