In this world, there are a lot of “There-are-two-types-of-people” situations, but when it comes to pebble ice, really, there are two types of people. There are those who adore those tiny little nuggets, and there are those who don’t care about ice.
I’m one of the former. This type of ice is the best ice, period, and Sonic does it perfectly. Each nug is the exact right size, somewhere around 3/8"-1/2". There is no better type of ice in this universe more enjoyable to crunch down on, and no fast-food restaurant more reliable to enjoy it at.
