PA is pretty amazing but you have to understand its limitations.
Extremely narrow aisles makes shopping at PA du Fort an adventure. And by "adventure" I mean shopping in a developing country. It can be very frustrating unless you shop at off-hours. Further, the type of people that PA attracts are usually spatially unaware and can be oblivious to the navigational difficulties presented by PA's small floor-plan.
Along with Segal's, PA has the lowest prices on produce that you will find in the city... unfortunately, this is because it's old stock from other grocers and is expectedly a little shifty. In 2015, I have found nice red peppers for $0.99/lb and bundles of asparagus for $1.60. That is pretty crazy. They have a great cheese section with a large selection and seemingly half their stock marked down. Likewise, their meat section is quite affordable in comparison to other grocers.
Though they have at least 10 ill-tempered cashiers on staff at peak hours, the lines still move fairly slowly. Pro tip: avoid lines with delivery orders, identifiable by small pastel-coloured forms being filled out and cardboard boxes with loud taping, and you will be out of there in record time.
