Kama (or Cama) coffee at RT Mart 1 in Neihu do their brews very well. Not too strong. It’s small but there are seats and go at the right time (like avoid weekends etc.)
Here’s the key: they have two espressos. The basic one is old-school (leaning to the bitter side) and IMHO not especially impressive. The other (chuang yuan) is fruiter and pairs really well with milk.
If you want to make sure to get the chuang yuan beans in your drink, try Louisa’s flat white, as that always has it. Or ask for a chuang yuan latie if you like things milkier.
The key is to distinguish the so-called “Third Wave” Lousa shops (newer, bigger, better layout, operated directly by the company) and the older franchises (often tiny, usually no washroom, with a more limited—or no—selection of sweets).
The “Third Wave” stores are such a leap forward that they seem almost like they are a different company.
