Bullet points. The food was good. The service was not at all. Don't waste your time or money. There are better options for a traditional Laplandian dinner in Rovaniemi.
Review of much better option here, finishing with a compare and contrast with Nili. https://www.tripadvisor.com/ShowUserReviews-g189922-d7980820-r894819867-Arctic_Restaurant-Rovaniemi_Lapland.html
I...had high hopes for Nili, based on reviews. Before we left the States, I tried to make a reservation online and was unable to. So I emailed and got a prompt and courteous reply, confirming our reservation.
Once we entered the restaurant, my hopes were dashed. I don't need dirty sheep skins and dusty reindeer antlers to set the mood. The tables were cramped. Our waitress was border-line rude. Our questions--it's a tourist place after all and we were curious about how reindeer is cooked, etc.--were met with "OMG do I have to answer this again?" disdain. They won't split a main course. And they charge for water.
Again, bottom line, this place isn't worth it.More
