Admission to the Main Stand is available, priced £4 for adults and £2 for concessions, while The Pilgrim Lounge will be open throughout the evening too.
Harry Limb was the man in the spotlight after bagging a hat-trick in the 4-2 victory over Anstey Nomads in the previous round and the Pilgrims will again be looking towards their talisman to topple their county neighbours.
City, meanwhile, have reached this stage of the competition courtesy of resounding victories over Matlock Town (9-1) and Leicester Road (10-0).
If the scores are level after 90 minutes, the match will progress to extra-time (and potentially penalties).
