The story
At Boon Nam on Lönnrotinkatu, the cooking stays close to its Thai roots. The kitchen sends out dishes that balance heat, sweetness, and acidity with the confidence of a team that knows exactly what it’s doing. Diners consistently mention the prawn salad, seafood bowl, and salmon in curry as standouts, along with a chilli platter that becomes a playground for the table’s sauces. For those who want the full picture, the tasting menu – available in a standard and a larger format – is the way to go, and the kitchen easily adapts it for vegetarians and vegans without losing any of the vibrant Thai character.
The service here is as noteworthy as the food. Guests describe the staff as warm, professional, and attentive – one reviewer noted how a server adjusted spice levels throughout the meal without being asked, making sure every dish landed right. That kind of care extends to the drinks too: alongside Singha and Chang beers, the cocktail list has its fans, and there are well-made mocktails for those who skip alcohol.
The space itself is relaxed and modern, with counter dining available for those who like to watch the action. It’s a setting that works equally well for a quick weeknight dinner or a long celebration – one recent birthday party was called “superb from start to finish.” The restaurant is wheelchair accessible and air-conditioned, and it offers catering for groups.
Boon Nam’s recognition as a Michelin Recommended restaurant in 2026 speaks to the consistency and craft on display. For a Thai restaurant in Helsinki that delivers on both soul and precision, this is the place.
