After a long walk around Swiss Camera Museum, go to this restaurant and have a rest here. But google users haven't given Café Glacier Olivotti a high rating.
Very nice ice cream, and friendly service. The cafe is on the main square and really close to the lake. I had stracciatella, cookie and strawberry. The stracciatella was good, cookie was fine, but the strawberry was particularly good as it was creamy strawberry ice cream as opposed to sorbet and the consistency was excellent.
