Pamela restaurant on bulevardi of Helsinki is a great place to chill with friends. When we visited it was nearly exclusively female visitors, but I can confirm that as a male, you're allowed to eat well too. 

Together with me in this Episode at Pamela is Sonja Heikkiä, who despite her young age has managed to see the world as an opinion leader on the future of mobility and transportation. We discuss how the future is shaping up to be and how to manage yourself when giving a public talk or appearance in television. 

For the Dinner, we had vegetarian food, although the alternatives for meat-eaters were delicious too.  

I'd call this restaurant a great option in case you want to meet with friends with chill atmosphere, without any pressure.
