The Banoffee Pie Cold Brew from the Cappuccino Cart in DCA $7.75 Magic Key Discounts Available Butterscotch Cold Brew topped with Banana Cold Foam and garnished with Cocoa Shavings. This was a very sweet coffee, and I wish I liked banana flavored desserts more than I do, because this one, while sweet, tasted like the right combo of sweet and coffee to me. My personal taste preferences don’t gravitate towards banana flavoring, but if you like banana treats and cold brew I think this one is a good bet to make you happy. The chocolate shavings on top were on point! 7/10 rating from me (keep in mind my banana disdain)
