I frequent this cafe most weekends, and the environment always puts me in a good mood by the time I leave. The presentation of the hot tea is perfect - loose leaf and the steeping is timed depending on the tea and in a big round mug. Same goes for the hot coffee drinks. They have their techniques down - great foam on the cappuccinos.
Their scones are worth trying even if you're not a fan of scones (I'm not but I always try the interesting flavors here). They come with a side of sweet creamy/buttery spread (clotted cream I believe it is).
This cafe hosts cool events frequently that are also educational. I attended a chocolate and coffee tasting event here where the woman who produces their chocolates (S.K. Frey - really good chocolate too! Buy a bar) talked about her chocolatier business and how chocolate is produced, and we got to try to the different coffee flavors paired with her chocolates. Also - Adda's coffee is brewed perfectly and has distinct flavors. You won't have the problem of the coffee smelling better than it tastes here, and you'll actually tell the difference between blends.
I hope to attend more of these in the future!
The space isn't huge, but there are a variety of seating types (group tables, bar tables by windows, cushioned benches by the windows) for whatever you're there for. Space can be at a premium, but the times I've shared tables with people I end up engaging in conversations and having such a pleasant experience.
The baristas are friendly and humorous and will definitely engage in conversation.
