The huge departmental store is located just next to the bustling Shinjuku train station, covering 8 storeys (including the basements and one rooftop, which I will explain later).
It seems that it caters to everyone in the family, selling all kinds of merchandise including fashion, bags, shoes, cosmestics, toys etc. Escalators and lifts are easily accessible, just like the washrooms.
The lower basements are mainly supermarket and food stalls, where you will be spoiled for choices. And this is one of the most crowded places in the departmental store at any time of the day!
In addition, several medium to high end restaurants are located on the 8th storey, mainly Japanese and Western cuisines. This is "quieter" than at the basements and prices are generally steeper.
And if you go up another floor to the rooftop, there is a plant nursery outdoor and an indoor pets stores, selling all kinds of accessories relating to pets, dogs, cats, fishes etc. And I especially like this "greenery" as it allows shoppers to take a break from the "noise and crowd" from the lower floors and indulge in some peace and greenery. There is also a cafe here which you can help yourself with some fingerfood.
If you are into shopping and staying near the train station, you will not miss this huge departmental store for sure! Make sure you have sufficient time allocated here (and cash too) for shopping!
