Yanlanlou once appeared in "A Bite of China" because of Lanzhou beef noodles, and became famous in the capital. Its founder is from Gansu, the beef noodle bloodline is pure, and "one clear, two white, three red, four green and five yellow" is implemented to the extreme. Unless otherwise stated, the noodles default to thin noodles, the thickness of which is the same as that of a toothpick; The soup is bright and slightly yellow, a few beef cubes and white radish float and sink in the soup, the dark red chili oil and coriander garlic sprouts are the most eye-catching, and the aroma is overflowing; Compared with Dongfang Palace, the seasoning is salty and oily, and the noodles have a more chewy texture, but they are not difficult to chew at all.

The store also serves Northwest staple foods such as gnocchi noodles, stuffed skin, pulled noodles and slurry water, as well as authentic mutton dishes. But if you just want to eat a bowl of beef noodles, Dongfang Palace, which has more branches and cheaper prices, is more competitive than Yanlan Building.
