Great Kosher food store. Friendly people; great Jewish vibe. Has most of what basics you need - not gourmet, few prepared foods other than spreads, but that's OK - pretty comprehensive, including yummy fresh baked goods including Challahs. Good selection of dairy products, kosher snacks. Only lack is a very limited selection of fresh chicken, no meat or fresh fish. It does have a frozen section and very nice fresh fruit and vegetables. They carry what you need in advance of any given holiday.
Best all-kosher grocery store in Toronto. And many sale items!
I will go out of my way to buy groceries from here. Excellent range of baked goods, dairy products, and fresh produce.
