On a hot summer day here in Texas, a Sonic on the horizon is practically an oasis and the reason is the drink selection. According to Sonic there are 168,000 possible drink combinations. And everyone I know has their favorite. Mine is the Diet Cherry Limeade; Route 44 size (that's big!).
Also of note are the cups and the ice. The Route 44 cups are made of styrofoam that might not be environmentally friendly, but that keeps my drink cool a long time. And the ice at Sonic is that little pellet ice that just can't be beat.
The 2 new drinks announced today, by the way, are flavored teas: red raspberry and peach.
