"Mercat a la Planxa, the colorful, sprawling restaurant on the ground floor of The Blackstone, gathers groups sharing giant servings of paella and pitchers of sangria. Adventurous diners can order a tapas tasting, while those visiting for brunch can mix traditional bites like patatas bravas and short rib empanadas with buttermilk pancakes and cheeseburgers. Make a reservation through OpenTable." - Sam Nelson
