Five restaurants in Haparanda across the border from Tornio: the town square hotel, a riverside classic 15 km upstream, sushi and Thai. Ratings and menu links.
Across the bridge from Tornio — same town in practice, different country on paper.
Haparanda is in Sweden, which changes three practical things: the prices are in kronor, the clock is an hour behind Finland, and the town shares a centre with Tornio anyway. Haparanda Stadshotell sits on the square, Leilani and Haparanda Sushi & Indiskt are a couple of streets away, and Cape East is out on Sundholmen. Kukkolaforsen, the most-reviewed of them, is 15 km upriver and a deliberate trip rather than a walk.
Sweden, not Finland: prices in SEK, and local time is one hour behind Tornio.
Kukkolaforsen is 15 km north along the river — plan a car.
Finland and Sweden are both in Schengen; crossing from Tornio on foot takes minutes.
