Ye Olde Cow is a dry-aged smash burger truck, with its base at 11 Portsdown Road in Queenstown. The patties are a secret blend of Black Angus beef, dry-aged for weeks and smashed to order on a hot griddle for crispy edges and a juicy centre. The double patty is 220g, and the burgers are halal certified. Recently the truck has been parked at lyf one-north, a one-minute walk from one-north MRT Exit B, and its schedule changes from week to week. The menu includes a signature burger with two dry-aged patties, American cheese, caramelised onions and house mayo, a double smashed burger, an old-school burger, and a grilled mozzarella veggie option. Shoestring fries come with beef fat cheese sauce. Plain fries are $6 as at 2026. Customers mention the smashed burgers, the juicy burger and the cheesy fries, and one calls it the best smashed burger in Singapore. Orders can be placed online or at the truck, and it is also on Grab and Foodpanda. Indoor seating is available at lyf one-north, and the truck also serves KidZania Sentosa.
