Editor’s Note

Last updated 21 Jul 2026

Our take: One Fattened Calf at New Bahru consistently delivers on quality, focusing on well-executed burgers with premium ingredients.

Reviewers frequently highlight the in-house baked potato buns and juicy, grass-fed beef patties as key differentiators.

The Butterburger is a standout, praised for its rich, clean flavour profile where thick slabs of butter melt into the patty, offering a unique and indulgent experience without being overly heavy.

The Cheeseburger is a solid classic, with many appreciating the well-melted cheese and soft bun.

While the truffle fries receive mixed reviews, the cheese fries with paprika are a popular upgrade.

We note that the prices are on the higher side, a point raised by several diners, but this is often contextualised by the quality of ingredients and the overall experience.

The space can get crowded during peak hours due to limited seating, but the service is generally described as friendly and efficient.

We think this is a destination for serious burger enthusiasts willing to pay for quality.
