Thanks, Jeff. I am really proud to close tonight's call by sharing a few of the team's recent achievements. In year 13 in the Shake Shack story, we are thrilled that our devoted fans continue to voice their love for our brand and our food. We were recently named the absolute best burger in New York by New York Magazine, the best burger in Boston by the readers of Boston Magazine, and named among the best six burgers in LA from LA Magazine. All of these, and so many other recognitions, just a few of the markers of the continued evolution of our brand strength, as we deepen our footprint across the country, and around the globe. 13 years into this journey, and we're bringing more excitement and loyalty to Shake Shack than ever. In addition, through the month of May, we continued our 5th Annual Great American Shake sale nationwide to benefit Share our Strength, No Kid Hungry campaign, and helped battle childhood hunger. We are so proud, and that with the help of our guests, our team raised almost $600,000, bringing our total in five years to just under $2 million. Not only are we donating to a great cause, but we were also able to drive incremental sales and traffic on future visits while doing it. Just another way we bring the life of boundless hospitality that differentiates the Shake Shack experience, and enriches the communities in which we serve. While we continue to grow in new markets across the country and around the world, we are constantly innovating around our core with new products that keep our guests coming back, thus ceaselessly reinventing ourselves in the ever-evolving landscape of our industry and the world around us. And we never stop asking the question Danny Meyer asked so many years ago when this journey began, whoever wrote the rule we should accept things how they are? We are continually challenging ourselves to think a little bit bigger, and go a little bit farther. We are really investing in building our team of leaders who are training the future leaders, who will lead our Company. Together we are executing on the plan. And as we celebrate the incredible milestone of our 100th Shack opening next week, we're positioning our team and our company to continue that growth, and to re-imagine what the next 100 Shacks will look like, and the 100 after that. We're thankful and honored, you've come along for the ride with us. Now operator, you can go ahead, and open the line for questions.
