Tuesday evening, the two dined at the Vitta restaurant in Rome just outside of the Fontanella Borghese Hotel.
Eyewitness Susan West told E! News that "[James] was there with his son having a nice quiet evening."
West was merely feet from the actor during dinner and she said that the two "looked like they were having a great father-son dinner and the waiters were all giddy and excited."
Gandolfini was originally in Italy to attend the Taormina Film Festival and was rushed to the Policlinico Umberto I hospital after his 13-year-old son found him collapsed in their hotel bathroom.
The hospital's ER director said the actor arrived at the emergency room "in a cardiac arrest, accompanied by ambulance of the 118 service [similar to 911 in the U.S.]." Unfortunately, "the attempts to rescue failed, and at 23:00 [11 p.m.] the patient died, formally died."
The three-time Emmy winning actor is survived by his wife, Deborah Lin, their 8-month-old daughter, Liliana, and son Michael, from a previous marriage.
