Many thanks to Andrea Tribulini for sharing a photo on FB. He posted the following with the photo:
Today in bike, Keanu Reeves came by.
He was alone.
He stopped for lunch in a farm in the area.
Looks like he ordered spaghetti at amatrixiana.
Note: Yesterday, I posted about the same photo posted by valebrugs on instagram here. At the time, there were no details other than the name of the restaurant. From the FB post above, we now have some details to go with the photo.
