Freaking hell it’s good. It smells exactly how it tastes and the price is awesome. A medium is quite giant and the #2 Americano (2 choices of beans; this one is the best one imo) is just divine.
Dont be put off since they trade reviews for 5 stars - they really deserve it. They don’t have English when you Google or Uber (can be annoying), but it’s 不二.
Bring your own cup and it’s like 40nt only.
So… how can we find this amazing coffee?
Is this the place?
I made a suggestion to google maps for the Xinzhuang location flagged by @Steve4nLanguage ; it was accepted almost immediately.

They’re all good, tried 2 branches so far. They stick with the recipe. Only one time I had leftover sour coffee out of like 100. Of those, 2 orders were wrong and the rest were flawless and fresh
I was tempted, then I realized it is in Xinzhuang… 
I’ve noticed that Xinzhuang store before, I’ll try it next time. I usually get a cup at the 7 across the street.
Just for reference, what other coffee shops/providers are you comparing to Bruno’s? Do you normally buy your coffee drinks at 7/11 (or similar), Starbucks, Cama, etc.? Is the medium you mentioned a latte?
