I agree, it is rather a canteen than a restaurant. Busy and a bit chaotic during lunch hours, when I happened to go there too. Service is ok, not friendly though.
And in my opinion you should not call a restaurant vegan if you serve dairy product. I see it as dishonest. Non vegan items are not marked, only Finnish customer recognize them.
Going there was a bit unpleasant experience for me so I chose rather going to some omnivore but vegan friendly places after the first time.
Cons: only casual food, no gourmet, dishonest, they are not full vegan, busy and chaotic
