We've been coming to Yan's for seven years at this point, when it used to be in Lafayette.
Now it's moved to Orinda, over by the library. Same wonderful owners, but the waitstaff has changed, and they're all new, which can lead to some slower service, but nothing that is too horrible.
I always get the twice cooked pork, which I ask for with less sauce, but it's seriously delicious. I definitely recommend it.
Come during lunch, where you get a tasty salad and egg drop soup with your order!
