We've been ordering from Zaws for over 7 years. We have tried many asian places in Pittsburgh and we keep coming back to Zaws.
The food is fresh (that's why it takes close to 40 minutes) not microwaved or just recooked like at most asian places you see.
Best general tso chicken and Mongolian beef by far. The owner, Sonny, is the nicest man you'll ever meet and know your name by no time.
Great place! Great food! Great people!
