I've used Downtown Camera for the past ten years. Their work is good, and (importantly) consistent. Prices aren't crazy either, which helps. I was just in today, and was very happy to see it busy with analog photographers. There was a line of three other people in front of me at the processing desk, and people were buying lots of film. The shelves were busting with more film (35mm, 120 and 4x5) in stock than I've seen in ten years. Lots of big posters up trumpeting shooting film, with deals on Ilford product.
I heartily recommend them.
