Whether I get home from work late or on the weekends - this store always is always open to satisfy my needs (yep - 24/7 location). At moderate prices and a decent selection, that is somewhat that I appreciate a lot.
There are a couple of downsides though - like the produce section where you either can't be picky or have to know what you buy. For example out of their ~4 different kinds of organic apples, two of them taste awful in my opinion. You'll probably find moldy stuff once in a while and the discount fruit is often slightly squashed or at least overripe. Also, I think it's unfortunate that old bakery ware is only 1$ off and not -50%.
And I guess as to be expected from a store like this, the people at the checkout are extremely unfriendly.
To me, these downsides seem like a small price to pay for the great location, the 24/7 availability and the decent prices. But if you don't live nearby and have the chance to shop conveniently somewhere else, you might not be as excited about this store.
