I only shop here on occasion, but when I do, I am quite satisfied.
The store is very large with a wide array of offerings. It is a good place to go to if you are looking for various ethnic foods or sauces. One of the best deals they have (which appears to be a standing deal) is a whole cooked BBQ chicken (halal - if that is a consideration for you) for $6.97.
The service is not always consistent. Sometimes the staff are incredibly helpful and will take you directly to an item that you ask for, and sometimes they just grumble the aisle number to you in an unhappy manner. Despite this, I find that the cashiers are always quite pleasant.
