Keanu appears to still be in Italy.
Many thanks to valebrugs for sharing a group photo with Keanu at Agriturismo Piandimolino
on instagram. The photo was posted about an hour ago and was taken in the restaurant. From their website, Agriturismo Piandimolino is an old stone house that now serves as an inn and has a restaurant on site.
It Looks like Keanu and Gard are travelling separate from Heath Cofran who posted a photo at Restaurant Landenberg in Turbenthal, Switzerland on instagram.
Update: Been on the road. The poster indicated further down in the comments left that Keanu was at the restaurant for lunch today, September 13.
