Qiao mian jiao tuan ($5), offered at Biang! but not at its modest Xi'an Famous Foods siblings, is a thick, warm buckwheat pudding. The menu notes that it is "similar to Japanese soba-gaki," which occasionally is served in sweet dishes, but this Chinese pudding is decidedly savory, owing to a soy-sauce dip spiced with mustard oil. I imagine it will be a popular accompaniment once the liquor license comes through.
