Our take: Alchemist at the Khong Guan Building is consistently praised for its coffee quality and distinctive industrial aesthetic.
We see a strong preference for the original outlet among patrons, who appreciate the high ceilings and raw, open feel that encourages a slower pace.
While the location in Toa Payoh's MacTaggart Road is noted as being 'out of the way' by some, the atmosphere and quality of the beverages appear to compensate for the inconvenience.
Reviewers frequently highlight the 'consistently good' coffee, with specific mentions of the Flat White for its rich aroma and flavour that holds up even as ice melts.
The Iced Black is also commended for its bold, prominent roasted notes without acidity.
While one reviewer noted a preference for dark roasts over the available medium roasts, the overall sentiment for the coffee is highly positive.
We think this location is ideal for those seeking a quiet respite with a well-made coffee, especially if you appreciate a strong, undiluted iced coffee.
It's a destination for the coffee and the space, not just a quick stop.
