This is a LOVELY Japanese store but it is admittedly small in real estate. All of their products are Japanese import, so they're genuine products that people buy on day-to-day basis for ages +25 & up.
Considering it is in Kensington Market, buy an Onigiri but don't judge the prices. This is a hidden gem for something unique even in a culturally rich neighbourhood.
Overall, I recommend spending some time at Sukoshi Mart and buy at least 1 thing for yourself or friend!
