As to whether I appreciate the style of the Dolce ristretto, the jury is still out, but I believe I'm on the right track with how to handle the coffee.
Rubbery, in espresso, usually comes from Robusta, which is also present in the Vivace blends.
I suggest you try a bunch of other coffees, especially single origins, before you conclude that the effort you need to put into pulling a good shot with Vivace's blends is worth the effort.
I have a number of single origins, and other blends, that I have used over time which are not particularly finnicky and which to my taste provide more pleasure than anything I've ever been served at a Vivace cafe.
I do still go there when I pass through Seattle, it seems like it is necessary for some reason, but I don't feel any obligation to drink their coffee elsewhere.
