Definately NOT sugar free, BUT the coupon for "buy one sundae and get one free" or 50% off on any sundae is the best bargain in the "world". Rather than buy two sundaes for $6.99 each, we bought the $19.99 Earthquake. It was sooo much better than the Kitchen Sink at Beaches and Cream. 8 choices of ice cream, we doubled up on four flavors, same with the toppings, bananas, cherries, mounds of whipped cream and Ghiardelli candy bars. Since it was half price, it came to just around $10. We ate almost all of it and we were stuffed. There were four of us with adult sized appetites I should add.
