Wendy's is doing away with the 'Biggie' drink size and returning to the terms everybody else uses: small, medium and large.
The difference is, though, that Wendy's us increasing the size of all their drinks. What was medium is now a small, etc. So now, small is a 20 ounce drink, medium is 32 ounces and a new 42 ounce size is a called a large. I'll say! 42 ounces is 1.2 liters (or 5 1/4 cups... a third of gallon). Wendy's will still sell a 16 ounce drink on its 99 cent value menu.
But I guess giant drink sizes don't have to matter.... if you order a diet soda!
And FYI, at Wendy's you can substitute a bottle of Dasani water for a soft drink (and you can substitute items such as a side salad, chili or yogurt and granola for french fries, regardless of the combo size).
