Its funny you should bring up this topic. I spent last weekend dining at The Lake House Daylesford which I believe is very well rated (2 hats I think) and serve Vittoria.
When we arrived I straight away noticed a Vittoria coffee label and didnt hold much hope. After 3 hours of gastronomic delight, I was inevitably asked would you like a coffee sir. I had been watching the Barista during the evening and witnessed some sink pours and grinder adjustment so I was hopeful an espresso wouldnt sour the evening.
When it arrived it was in fact 30mlsish with thick crema (a little light but acceptable) and the taste was good. It had quite a smooth non-bitter taste but rather bland not an exciting taste sensation a CoffeeSnob is accustomed to, but quite acceptable. At that point I was a very happy man.
Breakfast I quickly ordered another shot which proved to be visually very similar but extracted by the wait staff rather than the Barista and proved to be swill.
Personally I eat regularly at highly recommended restaurants and essentially I am there for the food, service, experience etc that a restaurant provides not for the coffee. As long as an experienced Barista is behind the machine 99.9% of the population couldn’t discern the quality of espresso served and probably doesn’t care either. I think the reviewers lack of apparent coffee knowledge is consistent with its audience, the dining public not the sipping public.
For the record I though $7 for an espresso was a little step.
