Guilin Mifen 桂林米粉 (Guilin rice noodles) is the most popular speciality of Guilin and surrounding district. In fact they can be found all over the province. Almost every street has a Mifen restaurant (shack) and they are very popular as a breakfast dish, although they can be eaten at any time. There is a 24 hour noodle shop at the end of the lane where I live.
They are spicy and very, very cheap.
They are not the only local noodle dish, however. I live in Liuzhou, 150km to the south of Guilin. Here, the speciality is Luosifen (螺蛳粉) , which is similar to Guilin Mifen but the soup stock is made from snails.
I've never known anyone to make Guilin Mifen at home. They are so easy to find and so cheap.
