The Comcast Center faces a half-acre public plaza. The plaza, designed by Lucinda Sanders of OLIN, sits over underground railroad tracks. It features a seasonal outdoor restaurant, Plaza Cafe at Table 31, that is sheltered by a trellis. Between the cafe and the building entrance is a choreographed fountain designed by Wet. The tower's entrance is a tall winter garden. The winter garden entrance directly connects to the underground concourse of Suburban Station. The building also has a lobby entrance that leads to the Arch Street Presbyterian Church adjacent to the tower.
