The city hums before the doors open: taxis inhale and release into avenues, the polished face of the Chrysler Building catches the morning light, and the marble concourse of Grand Central waits like an old theater ready for its scene. On this three-hour walk through Midtown you move with the city — from Bryant Park and the New York Public Library to the cinematic sweep of Grand Central, along Fifth Avenue to Rockefeller Center and St. Patrick’s Cathedral — and end inside a live gospel service that brings voice and rhythm into the urban grid.
