Glad I chose this place today over a different, slightly higher rated shop (maybe tomorrow).
I went here because they're also a roaster, so I know the espresso is probably good and more freshly roasted than other places.
Unfortunately, for my eaistline, they were also baiting me with chocolate chip cookies next to the ordering point. Couldn't stop myself - I'm weak.
Solid products, latte art and really friendly staff.
Second visit in two days, last day in Porto, and a bag of Columbian to take home.
