Hands down the best thing about the Sobeys on Dupont is the fact that it's open 24 hours. I can hit this place drunk at 4:00 in the morning and pick up all sorts of goodies to take home with me. The best overnight staff member is Dora -- she has seen me in various states but she is always so lovely and pleasant. I'll be sad if she ever stops working there.
This Sobeys used to be an IGA a few years ago, so the place has renovated quite a bit, but it's still not as modern as some of the larger grocery stores in the city. I personally prefer something like Loblaws for ascetics or No Frills for the prices, but I will take anything that's 24 hours.
