DAFO used to be the best lab in town, they had a dip-n-dunk line of E6/C-41, and they processed B&W in XTOL or HC-110. Always same-day, 1 or 2 hours time of processing. When I began photography, they were developing my first negatives, and it was my reference for B&W. Plus, they were the last place in town I know of who could do real projection RA4 prints.
Like everything else, they went to the dustbin, sold their equipment, and closed the place, but I remember the smell of fixer in a particular Old Montreal alleyway...
