Yeah, that's 'cafe Corsari'.
Damien was on it as well (october 2014, no interview though)
It's filmed very close to where I live. (Here's the Hozier interview

The woman with the shocked expression says that she thinks it's 'AMAAAAZING', so she's just very impressed, i think.
This is what she does for a living

So i guess it doesn't take much to impress her...
