Beef noodles add spice to US food market

Great grub is China's best ambassador, says chain owner, a native of Guizhou

When you stroll down the streets of Silicon Valley in the United States, you might notice a newly opened restaurant called Mifen Prince.

Despite the odd name, once you step inside, the tangy, fermented sour broth will transport you to the misty forests of Southwest China.

The chain belongs to Chen Yuzhu, 40, a native of Guizhou province. Its signature dish is Huaxi beef rice noodles, an everyday food across the province, made with stewed beef, beef broth and vegetables.
