Jimmy’s Downtown, located on the eastern fringes of 57th Street sits among the haute wine shops and poodle-grooming spas of Sutton Place. The design of the bar lounge is flanked by low-slung banquettes on one side and a glimmering bar on the other, so walking to your table feels a little like strutting down a catwalk in the midst of a zany, salsa-inspired fashion show.
