Patrick Dempsey and his wife Jillian's relationship wasn't rebuilt in a day ... so they picked the perfect place to toast their reunion.
The newly still-married couple had a romantic dinner Saturday at Al Ceppo in Rome, and looked like a couple of kids on a first date again. As we reported ... her divorce petition was officially torn up, 10 days ago.
The celebration included Jill fork-feeding him. After 17 years, they're cool with sharing a little saliva.
