まいばすけっと　三軒茶屋店

This is my go to supermarket. This mini supermarket is owned by the large chain retail shop, Aeon. Situated on the corner of Kannana-​dori (Tokyo’s ring road) and Setagaya Road, hidden in the back streets between Sangenchaya and Komazawa Daigaku station, is this little corner shop.
As most supermarket in the area closes around 9−10pm, here they’re open until midnight. Although, it only has about 3 rows of products, most of what you need from a supermarket is pretty much covered.
This is the perfect last minute store where you will find 5 different types of tofu, 3 types of milk, a selection of bread and small packages of vegetables (great for those cooking for one).
Tip: their beverage section (alcohol, soft drinks and juices) are usually cheaper than other regular supermarkets.
