Shop til you drop

When.
Most shops are open weekdays 9-21, Saturdays 9-18.
In summer and 4 weeks before Christmas even Sundays 12-21.
What is open on other Sundays ? Very small grocery shops, kiosks, petrol station shops, and the shopping centre below railway station 12-22.

Where.

• Touristy souvenirs and design kitchenware etc. along Esplanadi.
• Clothes from Swedish chains and similar (H&M, Kappahl, ... ) along Aleksanterinkatu or in Itäkeskus (by metro).
• Serious kitchenware in Arabia Factory shop (tram 6)
• Furniture shops seem to be along Ring road III. Two Ikeas are roughly there (one in Espoo another one in Vantaa), and the rest mailny between these two. Petikko (bus 360, 361) has a bunch (Asko, Isku, Soffatalo, Lundia, Eurokangas...). Lanterna mall between Itäkeskus and Herttoniemi is the easiest place to access without private car.
