What this Nishi-Shinjuku branch is like
This is a branch of FamilyMart on Nishishinjuku in Nishi-Shinjuku, a short walk from Nishi-shinjuku-gochome station. Walk in and the first thing you notice is the space: the aisles are wide enough to move through without turning sideways, which is not always the case for a konbini in this part of Tokyo.
The tortillas are what to buy. A pack carries 13g of protein, which makes them an easy thing to take back to your room or eat on the go. Beyond that, the shelves hold the usual konbini range of snacks and bento, and the spend stays between ¥200 and ¥1,000 for either.
The shop runs on self-checkout. Near the microwave and cafe corner there are only a few tables, so people warming a lunchbox and people adding sugar to a coffee end up waiting for the same small space.
There are no toilets and no eat-in seating, so plan to take your food elsewhere.
It suits you if you are staying nearby and want a quick, late or early bite without hunting for an open shop. The 24-hour schedule is the real draw, and the ¥200–1,000 band keeps a meal or a snack simple.

Who is this for
This branch suits a traveler landing late or leaving early, since it stays open 24 hours and you can walk in at any hour for a bento or a snack. It also works for someone staying in Nishi-Shinjuku who wants a quick stop without a detour, with the tortillas as the item to pick up. If you need to sit down and eat, plan to take your food elsewhere, as there is no eat-in seating.
If you want a proper seafood or sushi counter and a fuller grocery shop rather than a quick konbini stop, Aeon Food Style Nishishinjuku is the nearby option for that.
The verdict
The 24-hour schedule and spacious aisles make this a convenient stop, but the tables near the microwave are too few, so it suits a traveler who wants speed over comfort.
