From "Cool-A-Coo comeback: A chocolate-covered win-win for the Dodgers" by Bill Shaikin at the LA Times:
Mark Walter lives in Chicago. Stan Kasten spent most of his adult life in Atlanta. Peter Guber is an L.A. guy.Dodger fans of a certain age will have fond memories of the Cool-A-Coo ice cream sandwich, a largish puck of vanilla ice cream between two chocolate-chip cookies, all covered in a chocolate shell. Biting into a frozen Cool-A-Coo was akin to sinking your teeth into a brick, but a few minutes in the afternoon sun turned the cookies surprisingly soft and chewy, which made the whole thing a delight. I'm trying to eat healthy nowadays, but a Dodger Dog followed by a Cool-A-Coo still sounds like a winning combination.
So, when Guber pitched a nostalgic idea on behalf of L.A. fans, his partners in the new Dodgers ownership group listened.
"Curly Coo," Guber told Kasten. "There is nothing like a Curly Coo." [...]
Kasten, the new Dodgers president, eventually figured out what Guber had tried to say. When Kasten met with Levy Restaurants, the company that handles the Dodgers' concessions, he demanded better food, shorter lines and Cool-A-Coos — if, that is, Levy could find them.
"The Levy people are tracking it down," Kasten said. "They have been sending me updates on the Cool-A-Coo front."
