Best Bun Cha in Hanoi : 34 Hang Than Street, Hanoi Possibly the most delicious food available to man, bun cha is the lunch of choice all over Hanoi. Pork patties and slices of pork belly are grilled over hot coals and served with fish sauce, tangy vinegar, sugar and lime, which, when combined, creates a sort of barbecue soup that is eaten with rice vermicelli and fresh herbs. Accompanied by deep-fried spring rolls, this calorically rich dish is served with garlic and chilies on the side for an extra kick. Bun cha is my favorite lunch dish of all – barbecued pork in a sweet and sour soup with bun noodles and herbs on the side. Another favorite came from Bun Cha 67 Duong Thanh.
