Stephen Starr's Rittenhouse steakhouse in a former 1920s brokerage room — soaring ceilings, dark wood, leather booths, the kind of room built for closing deals and marking occasions. Prime dry-aged beef, a deep wine cellar, a serious raw bar, and the polished old-money service that distinguishes it from newer steakhouses. For a Philadelphia steakhouse dinner with genuine 1920s gravity.
