It's coming... We snapped this photo, complete with "Shack in Progress" sign, Monday afternoon of the upcoming Tysons Shake Shack, located on the new rooftop terrace between Lord & Taylor and Hyatt Hotel. A Shack rep tells us the joint is still on track for an early August opening but, as of yet, there's no firm date. In the meantime, we lie in wait.
