Boulevard Social, Helsinki, Finland: This restaurants serves some killer food with Mediterranean flavours but with a twist. The focus is more on North-African and East-Mediterranean cuisine and so is some of the wines as well.
Johans: Summer restaurant in my hometown Porvoo. Simple and tasty food + a very decent wine list. Situated in the beautiful old town by the river. For dinner make a reservation. Open only during summer.
Pure Bistro: Modern bistro in the city center of Helsinki. Tasty dishes made from fresh ingredients. Lunch or dinner you should be able to get some quality grub. There is also a bar if you feel like having just a drink or something small to eat.
