The hand-spun milkshakes—offered in the classic trio of chocolate, vanilla or strawberry—go perfectly with the vintage Americana vibe at this new Washington Avenue burger joint. Piled high with whipped cream and with a thickness just shy of spoon-worthy, Graffiti’s milkshakes have become instant classics. Looking for something a little more 21st-century? There are peanut butter and Oreo versions too.
