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.

Visitors can walk, jog, or cycle on the top of the wall, enjoying the magnificent views of the city and its historic gates. It is a significant cultural and historical site, beloved by both locals and tourists.
