An iced mocha cola is similar in spirit to a chocolate egg cream, an NYC staple that contains neither egg nor cream, but is made with whole milk, chocolate syrup, and seltzer water.

The same is true for Dunkin' Donuts' drinks; order a Mocha Iced Latte with nonfat instead of whole, and you'll get much less fat (0.5 grams instead of 6 grams) and fewer calories (180 instead of 230).
