Reflected in this shop window is the Chiesa San Trovaso in Dorsoduro.
But, I had neglected to take a photo of the outside of this shop. Now, thanks to Fausto who graciously allowed me to use one from his blog http://alloggibarbaria.blogspot.com.au/2012/05/enoteca-cantinone-gia-schiavi.html I can reveal which shop it was. Next time, I’m going in, especially after reading what Fausto had to say about it. .
