Nothing says summer more than Red Robin's Speckled Lemonade. We tested them out on the show and all we can say is “Delicious”!! Make sure to stop by Red Robin today for National Lemonade Day. They will be giving away free samples of their Freckled Lemonade between 11am and 3pm at all locations across Colorado. While you are enjoying your drink you can make a donation to their national charity partner, Alex's Lemonade Stand. The non-profit is dedicated to finding better treatments for children with cancer.
