Han Dynasty looks ordinary. The original is an unassuming restaurant in a strip mall in Exton, with beef-and-broccoli on the menu. Behind the facade, however, is a treasure trove of authentic Chinese cooking and a friendly staff happy to guide anyone through the menu. The chef specializes in spicy Szechuan — lamb with cumin, Dan Dan Mien noodles — but also offers milder Taiwanese favorites, such as lion’s head meatballs and three cup chicken. The new spot in Montgomery County expands the "dynasty" - and this is an empire we're grateful for.
