"Disclaimer: Mom should be a fan of heights for this Rosslyn brunch atop a 32-story skyscraper. The months-old perch 400 feet high plans to import a brunch buffet from Arlington neighbor Barley Mac. Each $250 ticket for a family of four includes admission and a tour, a bottle of Champagne or rosé for the reserved table, access to the Instagram-friendly outdoor terrace overlooking D.C. landmarks, and a commemorative wine glasses to take home. Seatings are available starting at 10 a.m." - Tierney Plumb
