One Fattened Calf (One-North)

One Fattened Calf is a small burger shop on the ground floor of Galaxis, an office and research building in one-north. Husband-and-wife team Joe and Corrine opened it in September 2021. The brand has since added a second outlet at New Bahru on Kim Yam Road.

The kitchen makes almost everything from scratch. A small bakery at the back turns out potato buns each day. The team grinds its own grass-fed beef from New Zealand and makes its own sauce and pickles. Each patty weighs 150g and contains no fillers.

What to order

The menu is short and built around a handful of burgers. Each one comes on the house potato bun, stamped with the letters OFC.

• OFC Cheeseburger: the classic, with cheddar, charred and raw red onions, house pickles and the OFC special sauce
• OFC Burger: the same build without the cheese
• OFC Butterburger: topped with a thick slab of cold butter that melts into the hot patty
• OFC Goldburger: finished with pulled beef brisket made in-house
• OFC Veggieburger: the meat-free choice, with a soy-based patty

The patties are smashed on the grill and given a quick blowtorch before serving. This gives them a charred edge while keeping the middle juicy. For sides, there are regular, cheese and truffle fries, as well as potato tots. To drink, look out for the OFC Golden Lime Slushie, a tart and icy lime drink.

The setting

This is a small, casual diner rather than a sit-down restaurant. Seating is limited, and the open kitchen lets you watch the burgers being put together. It suits a quick, casual meal more than a long dinner.

Popular items can sell out on busy days, so it pays to arrive early. If the seats are full, takeaway is an easy option. Towards the end of each lunch and dinner service, the shop switches to takeaway only.

Good to know before you go

• There are no reservations. Staff seat a group only once everyone has arrived.
• You can order online for takeaway through the official website.
• The shop says there is no pork or lard in its food.
• Opening hours can change, so check the One Fattened Calf website before you travel.
