Let the kids can romp at the park (with swings and sand box) across the street while one parent shops for Swedish dinner supplies such as shrimp salad, cooked crab, freshly foraged forest mushrooms, and lingonberries at the specialty grocery store which includes a butcher shop, fishmonger, deli and greengrocer. The parent babysitting will probably see well-dressed Swedish parents having a craft beer from Urban while pushing a kid on a swing and simultaneously catching up on gossip.
Alternatively, wear your small folk out at the park then sit down at the always-buzzing restaurant for family dinner. Although it looks like a bar, the friendly staff wont bat an eye latching high chairs onto the tall tables. The fare is a combo of Swedish comfort food (husmanskost) such as cured salmon, sausage and cabbage, peel and eat shrimp and fish stew, alongside a more international interpretation of charcuterie and mains. The craft beer and cocktail list is a good intro to small batch Scandinavian makers.
