Hietalahti

This is a must-​do in Helsinki especially if the weather is nice. We ate breakfast (delicious rice porridge and meat pies) sat in the sun and listened to polka music played on an accordion. A lovely experience.
The market itself is fairly small, but in the summer includes both indoor and outdoor vendors of all varieties from crafts to antiques, baked goods, meats and farm fresh produce. It took us about an hour or so to eat breakfast and walk around.
Worth checking out. Much less touristy than the South Harbor market square at the end of the esplanade.
