Freckled Lemonade — a blend of sweet strawberries and tangy Minute Maid ® Lemonade with free bottomless refills — has been Red Robin's signature beverage for more than 20 years, and is the perfect drink to honor National Lemonade Day. "Freckled Lemonade is part of Red Robin's heritage and a true menu favorite, so partnering with Alex's Lemonade Stand is a perfect fit," said Denny Marie Post, Red Robin's senior vice president and chief marketing officer. "We're proud partners of the Foundation year-round and hope our guests will help us further support this cause on National Lemonade Day." Alex's Lemonade Stand Foundation was created by four-year-old cancer patient Alexandra "Alex" Scott (1996-2004) who began raising money and awareness to help find a cure for all kids with cancer by selling lemonade at her own front yard lemonade stand. Alex's mission continues today through the work of Alex's Lemonade Stand Foundation, which Red Robin is proud to support. During opening week at new locations, all proceeds from Freckled Lemonade are donated to Alex's Lemonade Stand Foundation to support the search for a cure for pediatric cancer.
