甘肅蘭州128元“黑珍珠”牛肉麵vs 8元最辣牛肉麵，那個香？

Today we tried three different beef noodle soup places, starting from the spiciest at Guoyi Beef Noodle, to the most traditional at Bai Lao Qi Peng Hui Beef Noodle, and finally, the most expensive one, Guan Jin Cheng Boutique Beef Noodle. 今天我們連吃三家牛肉面，從最辣：国义牛肉面(陇能家园B区店)；到最傳統：白老七蓬灰牛肉面·清真(总店)；到最貴的牛肉麵：观金城·清真精品牛肉面(天水路店)
