Before you can shop here you need to get a customer card. This can either be registered to your business or, as a foreigner, you can get a day card against your passport. As the name suggests; some items need to be purchased in bulk, the price tags will inform you of this. Metro is large and can be a bit overwhelming but you will find items here that maybe you won't find elsewhere. Probably the best fresh fish counter in Sofia and largest wine and spirit selection. The large freezer section also offers plenty of pleasant surprises. They have developed their bio and health food section in recent years. If you are looking to furnish your home you can also find bedding, towels, crockery, garden furniture and more here. Works 24 hours.
