Yu Xin is my favorite Cuancai in Beijing, I used to get there twice a week. Shui Zhu Yu is recommended, of course is not that popular recently but I still love it. Yu Xin has so many subbranches here in Beijing but no matter which one you choose, I'm afraid you must wait for a while since it is so welcomed in the city. The price is less than South Beauty but taste super good! It's really hard for me to pick out a dislike dish there.
