Editor’s Note

Last updated 3 Aug 2026

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.

Loved the retro vibes here! Made a quick stop for iced latte. Both beans available today are medium roasts. It's good but I prefer dark roasts.

Pretty good quality white and filtered coffee. White with Fruity Cake Espresso is lovely, with soft aroma of orange, and smooth. Los Nogales, Colombia Washed Filtered Coffee is pretty good too, light…

The Best Flat White Award definitely goes to Alchemist! ☕️ Their Flat White is anything but “flat”—it takes you on a journey through layers of rich coffee aroma and flavour. Even as the ice melts, it…
