This is sort of a hybrid convenience/grocery store in the Church-Wellesley Village. There is one major pro...it's open 24 hours. So if you're craving ice cream after the bars close at 2 AM, then this is the place to hit up. In fact, I kind of wonder if most of their business takes place in the wee hours of the morning.
The one primary characteristic of their offerings is that it's expensive...more than Loblaw's, more than Rabba, more than Metro, more than Sobey's. The other suggestion is to avoid the produce...it's both rather gross looking and expensive.
In short, this is your drunk 2 AM kind of supermarket.
