Something tells me your wife picked the place. I recall you complaining about a bad dining experience in Tampere before.
Was her intention to go for a fine dining experience? If so, I suggest it would be worthwhile to do some research beforehand. It would be a great idea regardless of the plan.
She isn't much of a restaurant picker, it seems. I believe the risk of a disappointing experience is higher than usual in a place like Periscope. People come for "the view" and get ripped off. Note that I have never been to the place so I can't really know if it's actually a bad place. Just saying the risk is greater in a place like that.
If the view was something you really cared about, Näsinneula would've been a better choice. About 140 m above ground level, the view is unsurpassed by anything within >100 km radius. And it's widely considered to be a pretty good restaurant.
Consider Ravinteli Huber:
https://www.ravintelihuber.fi/en/
The website looks promising for meat lover. It's a little bit on the expensive side but not too much. Come to think of it, it's actually quite reasonable. A cheese burger for €12, probably a small one as it's listed among things like portobello and pistachios (€12), Huber's sausage and mustard (€4), grilled bone marrow (€5).
