Editor’s Note
Last updated 21 Jul 2026
We think One Fattened Calf Burgers delivers a high-quality burger experience, with particular praise for their beef patties and potato buns.
The Butter Burger, priced at $16.90, is frequently highlighted for its juiciness and flavour, though some note it's not available for takeaway.
The house-made pickles and well-seasoned patties receive consistent commendation.
Sides like the cheese fries and truffle tater tots are also popular, with generous cheese portions and crispy textures.
While the pricing is on the higher side for a burger, many reviewers feel the quality justifies the cost.
However, seating is limited, with only about 20 spots, leading to potential wait times during peak hours.
We also noted an isolated but concerning report of a rancid fry, which, while acknowledged as a one-off, is worth noting.
Despite this, the staff are consistently described as friendly and helpful, contributing positively to the overall dining experience.
The thoughtful packaging is a plus, making takeaway a viable option.
Overall, One Fattened Calf is a strong contender for a quality burger.
We'd recommend dining in for the full experience, especially to try the Butter Burger, and suggest visiting outside of peak lunch hours to avoid queues.
