On the other side of the street Gelateria K2 (which is pronounced Gelateria Kappa Due here btw) had a long line of gelato seekers. And the white chairs in the photo below are outside Caffe' 5, next to Caffe Moka, another excellent viewing and aperitivo spot. 

Via Bolongaro is the street on the right side of the restaurant Osteria degli Amici, in Piazza Possi. If you don't normally make a wander down Via Bolongaro in Stresa, you should start to include it on your walks. It's a normal residential street, used by locals as much as tourists. It is also where the Post Office, the Uffico Postale, is located.

There is a different band each Tuesday night throughout the summer season. This one played a great selection of blues, rock, and classics that pleased everyone in the crowd, regardless of their home countries. The music began around 8 PM, and finished a bit after 11, with an encore of U2's One Love. Definitely a fun, casual spot to hang out and enjoy Stresa on a nice summer evening.
