I had to warm a little to this place – its signature dish, ‘Biangbiang Noodles’, means you are trying to eat (with chopsticks) something that is like an enormously elongated and slippery chink of lasagna. At first I found it impossible to haul the stuff up more than about an inch out of the bowl. So the solution has been to have my head in the bowl while I slowly chomp it into manageable bits. But the taste and price have trumped the mechanical logistics. For 18 RMB you get a large bowl of noodles in a spicy sauce with veges, eggs, and some meat, plus a soup. Only a few dishes are advertised with photos, but there are many more options if you can read the Chinese.
The name of the place translates as ‘Xi’an Noodles’ and it is on the south side of the narrow Wenchangqiao Rd (connecting Chengxiang with Taiping Nth Rd, and to the east of Southeast University).
