Xiaojiahe area is a pretty good place find yourself hungry. Grandma Jin's is a spot I've always wanted to try but hadn't gotten around to because of all the other great barbecue and homestyle food in the area. I finally walked in the other day; it's a little rundown but they keep the place very clean. I wanted something green so ordered a Y5 plate of 凉拌折耳根 (cool mixed zhi'er gen). I haven't found an English name for zhi'er gen; it's green, flat leaves with a minty taste. ('Vietnamese fish mint' keeps turning up, but the plant does not taste fishy to me.) It came tossed with vinegar and a little oil, onion, and garlic. That day they also had cucumber, tofu, and wood ear available for the liang ban (cool mixed) treatment.
The handmade noodles ended up being almost exactly like bedspread noodles, and were really, really good. These are beef flavoured. Need to sample the 豆汤饭 (bean soup with rice) next time.
