The Pentagon has over 20 of its own fast food operations, including Subway, McDonald's, Dunkin' Donuts, Panda Express, Starbucks and Sbarro, among others.[76] A multibranded KFC, Pizza Hut, and Taco Bell restaurant opened in 2003, when renovations to the food court were completed.[77] Food services are managed by the Navy Exchange. The Center Courtyard Cafe reopened in the spring of 2008,[78] replacing the "Ground Zero Cafe" snack bar that was previously there.

The Pentagon Athletic Center (PAC), a fitness center for military and civilian staff, opened in 2004[79] adjacent to the north side of the Pentagon, replacing the Pentagon Officers Athletic Club (POAC) which had operated for 55 years in a structure between Route 110 and the parade grounds. Each year, the Pentagon grounds are a major focus for hosting the Marine Corps Marathon and the Army Ten-Miler running events.

There is a Meditation and Prayer Room in the Pentagon, which was dedicated on December 14, 1970, by Secretary of Defense Melvin Laird.[80] On September 11, 2002 the Pentagon Memorial Chapel was dedicated.[81]

In conjunction with the 1976 American Bicentennial,[82] the Pentagon began offering guided tours to the general public. Tours were suspended after the September 11, 2001 attacks,[83] but are currently available to the general public with reservations 14–90 days in advance.[84]
