No Frills is great! The shelves and freezers are always stocked, the fruits and veggies are usually quite fresh, and everything is well-priced. When they have sales, I tend to buy more than I should (but it sure makes sense at the time)!
Why go to another grocery store if you can fill your pantry and get fresh items here? I think you can easily save at least 25% off your grocery bill (if not more) when comparing to places like Sobeys, Loblaws, or Metro. I will admit, I don't normally pick up meats because they don't have our preferred cuts. Sometimes we will get the ground beef though.
I don't really like the parking situation since the underground lot isn't always accessible. If you can come at an off-peak time, you should be able to snag a spot above ground.
