The verdict
A high-precision espresso bar in Kaka'ako that's genuinely good for those seeking a perfectly pulled shot or one of their signature 'scuffins'—a hybrid scone-muffin that's a local favorite. The staff are knowledgeable and the black sesame latte is a standout. If you're looking for a quiet, spacious place to linger over a book or a full breakfast menu, this isn't it; the footprint is tiny and the seating is limited.
