"Nai Brother is a restaurant chain known for a singular dish that you can order a hundred different ways: the Sichuan soup, suan cai yu. The default version is sour, savory, and spicy: It comes with flaky white fish, like snakehead or tilapia, plus pickled mustard greens and a handful of chiles. That’s just the beginning. Diners can customize with an array of ingredients, like ramen noodles, dried beef, frog, and duck blood, as well as several broths available at different spice levels." - Eater Staff
