Editor’s Note
Last updated 3 Aug 2026
Our take: One Fattened Calf Burgers consistently earns high praise for its quality, juicy beef patties and well-balanced flavours.
Reviewers frequently highlight the Cheeseburger for its layered taste and texture, with particular mention of the patty's juiciness and slight char.
The buns are described as soft, buttery, and perfectly toasted, complementing the fillings without being overly heavy.
Sides like the cheese fries and truffle tater tots also receive strong recommendations for their crispiness and flavour.
While the quality is evident, we note that prices are considered to be on the higher side, with a bottled coke costing $3.80.
Seating can be tight, with limited dining space, especially during peak hours like weekend evenings.
We'd recommend going during off-peak times to secure a spot more easily.
Overall, it's a strong contender for a premium burger experience in Singapore.

What customers say
One Fattened Calf Burgers consistently receives high praise for its juicy, flavorful beef patties, soft buns, and well-balanced burgers, with many customers considering them among the best in Singapore.
While the cheese fries and truffle tater tots are popular sides, some find the prices high and portion sizes for sides small.
The limited and tight dining area can also lead to waiting for a seat, though staff are frequently commended for their friendly and attentive service.
