What is the proper ice fill level for a soda cup?

The proper ice fill level for a soda cup is typically three-quarters full, which allows for a good balance between ice and soda. This fills the cup adequately to keep the drink cold without overfilling it, making it easier for customers to enjoy their beverage without spillage. Filling the cup just below the rim with ice also enables customers to get the full amount of soda they expect when they order.

The goal is to create a drink that is cold and refreshing while also providing a reasonable amount of space for the soda itself. An ice fill of half a cup may not provide enough chilling effect, and customers might find their drink warming up faster than desired due to reduced ice. Therefore, a fill that is three-quarters ice is optimal for maximizing both the refreshing quality of the drink and customer satisfaction.
