Beef skewers, also known as bo nuong vi, are a popular street food in Halong. Thinly sliced beef is marinated in a mixture of soy sauce, garlic, lemongrass, and spices, then skewered and grilled over an open flame. The result is tender and flavorful beef with a slightly charred and smoky taste. Beef skewers are often served with rice noodles, fresh herbs, and a dipping sauce made from fish sauce, lime juice, sugar, and chili. They are a delicious and convenient option for meat lovers on the go in Halong.
