HELSINKI—Finland’s Parliament has one. Nokia has one. And now a Burger King restaurant in downtown Helsinki has its own sauna, too.

Hanne-Mari Ahonen, brand manager for Burger King in Finland, on Wednesday said the idea was to combine local traditions with serving burgers.

She says the restaurant had “lots of good feedback” since they opened last year, with groups of 15 accounting for some 60 or more people attending every week.

Customers do not eat in the steam bath; that comes after the big sweat.

“No, no, the sauna is for sweating it out, and our hamburgers taste all the better for it afterward,” she said.

The sauna costs 250-300 euros ($282-$350 for a group, depending on weekday or weekend). The meal costs extra.
