When a Cheesecake Factory moved into my suburban California hometown at the end of my high school years, there was one thing about it that excited me above all else. It wasn't the 33 flavors of cheesecake, or the choice of about two dozen entrées from every imaginable cuisine for $12. No, I was excited about their soda selection. Because for about two bucks, they'd give you a stunning 32 ounces of Fresca from the fountain—and then they'd give you free refills. I've always thought Fresca one of the most underappreciated citizens of the diet soda world.
