Market District's always clean and in general I have no complaints about the overall layout of the store. Employees are also generally nice and I've never had an issue interacting with them whether at the registers or on the floor.
Market District's major negative is that everyone in the world shops here so if you don't plan your trip here at a decent time, you could find the shelves bare. It also seems like such a struggle to make an in and out trip into this store, even when only grabbing an item or two. The prices can be a little over the top, so Market District's really just my backup store or if I'm looking for an interesting spice or sauce or something that I couldn't find at another store. They always seem to have it!
