The McDonald's 'McFloat' has been offered in many counrties around the world and was recently released in some locations in the United States.
The drink is offered with popular root beer Dr.Pepper and vanilla soft-serve ice cream. The McFloat is offered internationally in countries such as India, the Philippines and Indonesia and is a very popular dessert drink that is more indulgent than traditional fountain drinks. As of now, the McFloat will only be offered in New York and Seattle with the only flavor option being Dr.Pepper.
Considering the popularity of ice cream floats in general and McDonald's diverse drink menu -- it is likely that consumers will soon have more McFloat options in the United States once the beverage gains a following.
