The noodles are soft when the dish is served, and they slither right down your throat with ease. As you can see here, they do tend to clump together, so you'll have to do some good old fashioned Chinese noodle slurping. The soup base is oily and moderately spicy. The bamboo is the most distinctive feature of this dish, a bit sour and a firmer texture.
It's worth noting that locals do believe that the 'Old friend' noodles have some salubrious properties, possibly attributable to the spicy chili opening up your pores.
This dish shouldn't cost you more than about 10 yuan. And, it's available all over the Nanning city.
