Yan's Restarant specializes in Mandarin and Szechuan dishes. Located on the outer portion of Mt. Diablo Boulevard, Yan's has its own parking lot with ample spots. In keeping with the Feng Shui design principles, there is a small fish tank as you enter the door to attract lively energy and customers. The small restaurant is clean and simply appointed, with tables in the center and booths along each side partitioned by decorative glass dividers. Some specials include lettuce-wrapped chicken, crispy smoked duck and crispy prawns with salt and pepper.
