Many restaurants in the cramped alleyways between the vast textile markets serve just one food (fish soup, grilled duck, rice rolls, or crispy pancakes). We pass Pho Tung, widely considered Sapa's best pho spot, and Hai Há, known for its bún cha, pork belly. In addition, a deli, Am Thuc Viet, lets you pile up on dumplings, cold salads, grilled and braised meats, and pay by weight.
