As we all learned in junior high, but have probably long since forgotten, the ratio of the circumference of a circle to its diameter is 3.141592653 (etc.) - an infinite and constant number known as pi. Granted, the concept of pi is something best embraced by math geniuses, but the concept of pie is something we can all get behind. So in honor of National Pi Day, which of course is being celebrated on March 14 (3.14, get it?), Morton's the Steakhouse is offering its delicious key lime pie for the special price of...$3.14! And while mathematical pi is constant at 3.14, key lime pie definitely is not. The special $3.14 price is a one-day only treat, so put down your slide rule and come on in to Morton's for a little slice of heaven.
