In our interview with Rick Caruso, CEO of Caruso Affiliated and developer of famous Los Angeles malls like the Grove and the Americana, we asked him to divulge his favorite part of the mall. He answered with a riddle:

What does the 1717 number on the trolley at the Americana mean?

Or the 1759 number on the trolley at the Grove?

Caruso says if you guess the right answer, you’ll get a free Sprinkles cupcake — and we’ll hold him to it.
