Have been to Shaanxi Noodles (寻秦记) here at Tiong Bahru a few times and though I can’t say they are the best as we’ve had a mix of hits and misses, you get pretty decent Chinese food here. Prefer their 油泼扯面 more than their Biang Biang Noodles, the noodles have not bad a bite and were pretty springy with a slight spice. The larger portion is at $7. Skip their rou jia mo 肉夹馍 as it was unfortunately quite dry.
