Good specialty coffee, several yummy desserts to choose from (including vegan), as well as an array of coffee and coffee-related products, even merch. The barista (who was one of the owners, I think) was really nice to talk to; he even gave us a great suggestion for what to see while in Vienna.
The coffee shop itself is in a central location, very easy to get to, and the coffee (while a bit expensive) was well worth it, since “regular” coffee in the area isn’t much cheaper. There’s indoor and outdoor seating. We arrived very close to opening time and there were already several customers, so it’s nice to see that such a specialized place is a fixture in the local community!!
