Aihua Kudai Noodles Restaurant is a renowned local eatery in Xi'an, specializing in authentic "Kudai Noodles" (also known as Biángbiáng Noodles)—a iconic Guanzhong-style pasta. Located at No. 19 Dongmutou Shi (Main Store), this restaurant is beloved by both locals and tourists for its hand-made wide noodles and rich flavors. The noodles are stretched and slapped on the counter (making a "biángbiáng" sound) to achieve a chewy texture, served in large basins with savory toppings like diced potatoes, radishes, big meat pieces, and signature chili oil "泼"ed with hot oil.
