About this store
This is a branch of the Seiyu chain, standing on Asagayakita in Asagaya within sight of the station, and what sets it apart is scale: six floors, with the first two given over to groceries and fresh produce.
The first thing worth buying is the katsudon from the Trial range, a rice bowl for around 200 yen. Egg sandwiches cost 185 yen and come with a generous filling, an easy second grab. Hot pizza from the prepared food section is on the first or second floor, and the upper floors carry pet supplies, so cat litter is there at any hour.
Layout is what you notice next. Floor three holds daily necessities, four fashion, five household goods and toys, six specialty shops, and the range of facial cleansers upstairs runs wider than the nearby drugstore. Self-checkout tills, including the half-manned kind, keep the queue moving.
Prices sit a touch under what you pay at other supermarkets, and the Trial range is where the savings concentrate. Early morning around 6 or 7 is when produce is thin and drinks and yogurt are being restocked.
Come for the round-the-clock shelves and the cheap rice bowls rather than a full weekly shop.

Who is this for
This suits anyone arriving late into Asagaya who needs a real meal rather than a konbini shelf, since the food floors stay open all night. It also works for a traveler watching the yen, with the Trial range putting a hot rice bowl in your hands for around 200 yen.
If you want a proper prepared bento rather than a budget rice bowl, York Foods on Asagayakita is the closer call for quick meals.
The verdict
It is a workhorse branch rather than a destination shop, with thin early-morning produce, but the 24-hour food floors and Trial pricing make it the right stop for a cheap meal at an odd hour.
