Rapanui is one of the most iconic chocolate shops in downtown Bariloche. They sell decadent chocolate that you can purchase by weight - pick a variety to take home with you. They also sell pre-package bars and treats - my favorite is their version of the popular candy Marroc (chocolate and peanut butter, like a smoother Reese's).
On the other side of the cafe is their artisanal ice cream. They're well known for their excellent chocolate flavors but you can't go wrong with anything on the menu.
In the back is a cafe with light meals and snacks, a great spot to rest your feet or hide from dreary weather.
And as a random but fun addition, there's even an indoor ice skating rink inside.
