Shake Shack is celebrating its iconic crinkle cut fries with a first-ever deal that puts the spotlight on this fan-favorite classic. For one day only on National Fry Day (7/11), Shake Shack guests can score a FREE side of fries with ANY purchase using code FREEFRY via the Shack App, online at shakeshack.com, or in-Shack at the kiosk*. 

Shake Shack is also kicking Fry Day up a notch with a new merch drop - a Crinkle Cut Candle Set ($39), available in the Shack Store starting 7/11, while supplies last. The candles, shaped like Shake Shack’s beloved crinkle cuts and made with coconut wax and beeswax, provide the perfect candle-lit backdrop to your next Shack meal. Each set features 4 unscented taper candles and 2 white candle holders.
