Formerly a bank, this beautiful Neoclassical building modeled on the Pantheon in Rome dates back to the early 1900s. The Ritz-Carlton in Philadelphia looks like a stately government hall. Its interior is just as impressive as its columned exterior, with meeting rooms in the former vaults, grand ballrooms hosting many a wedding and a club lounge up on the 30th floor with a city panorama. The hotel’s Richel D’Ambra Spa is inspired by Balinese treatments, and the plush rooms are everything you’d expect from a Ritz-Carlton. Chef Richard Sandoval’s Latin-inspired menu at Aqimero focuses on a wood-burning grill and is served in an opulent dining room.
