Went there to do a passport photo and the whole process was quick and painless. He took a few photos of me, let me see the results, and advised on which one he thought worked best. After that, he said to come back in 10 minutes and it'd be ready. Easy peasy.
A no-frills kind of place, but he does a good job both quickly and efficiently. All told, the whole process took about 15 minutes and cost me around $12.
