OFC BUTTERBURGER (S$22/ combo)
Served with regular fries and a drink - OFC Golden Lime Slushie
Don’t why but the bun did not smell as good as it used to.

One Fattened Calf delivers a truly satisfying burger experience for those seeking quality and flavor in every bite. Their burgers are crafted with premium grass-fed beef and served on freshly baked toasted potato buns, ensuring a solid foundation for each creation.

The OFC Butterburger was the standout for me. If you’re a fan of buttery flavors, this burger is an indulgence you won’t want to miss. The 150g beef patty was perfectly juicy, complemented by the richness of the grass-fed butter. The charred onions, raw onions, and house-made pickles added layers of texture and tang, balancing the butter’s decadence.

The OFC Cheeseburger was equally impressive, featuring the same premium patty with the addition of melted cheddar cheese. The OFC special sauce elevated the burger with its unique tangy and savory notes, tying all the ingredients together beautifully.

The sides were just as enjoyable. The truffle fries were crispy, well-seasoned, and carried a delightful truffle aroma that wasn’t overpowering. The cheese fries, on the other hand, were a gooey, cheesy delight that felt like the ultimate comfort food.

The OFC BUTTERBURGER ($19.90 - combo) is a cheeseburger with its cheese replaced with two thick slabs of cold salty butter, which turned out soooo good. The combo comes with a refreshingly sour GOLDEN LIME SLUSHIE and fries which I changed to CHEESE FRIES (+$2.50). Good but wayyyyy too salty.

You are, the only exception, you are, the only exception.
For breaking the no eating in car rule. There will be serious regrets if you do not consume these triple friend fries on the spot. It should probably be a crime. Hands down.. the best IMO there is. Ok, something happened to their truffle oil recently and its a little off compared to before, but they are still 💯 (ok minus 5 for fairness)

Their burgers are also 🔥. For the same hefty price as 5 guys (how do they even justify themselves ?!?!?), I'd take this any day.

truffle fries were v nice and fragrant but portion v small :( lime slushie was good!

vv juicy and tasty burgers but also vv oily so can get slightly messy. they have a burger w a slab of butter in it as one of their specialties but i didn’t think the butter added much to the burger so i prefer their normal burgers
