If it doesn't taste good, don't buy it! I'm from Nanning, and my house used to be opposite Fu Ji Lao You. I ate there a few times a week. Listen to me!
It only has a light sour and spicy taste (then why don't I eat hot and sour noodles?!), and there is no sour bamboo shoots and black beans at all. There are only a few pieces of sour bamboo shoots in the soup.
(I know that authentic Lao You noodles don't put cabbage and beef balls 😂 workers put whatever they have in the refrigerator, don't dismiss my opinion because of this 😂)
