The reviews don't lie, 5 stars all around. The photographer was quick, efficient, polite, and knowledgeable. I went in to do a Canadian passport, though several people came in to do different international passport as and as I eavesdropped he knew the specific photo requirements for those countries as well.
The middle aged man who assisted me was Chinese (as we are in Chinatown) so he's able to assist in both Chinese and English as he speaks both very well.
Looks like the prices went up at bit, but I paid $9 (tax included) for 2 photos and a bonus one thrown in. He has the official stamp with the address and message to certify the passport photos.
Definitely check this out if you need to save money and get great quality photos!
