Yup, that's the place:

I had always assumed that the "ya" was 鸭 (duck), but the above link proves that I was mistaken; it is 雅, which means "elegant". I also had no idea that it specialized in Huaiyang cuisine, which I typically dislike. In any event, there are enough Beijing, Sichuan, and jiachang cai dishes on the menu to satisfy my palette (and fool me into thinking it was merely a fancier version of Xiaowangfu). You learn something new everyday.
