Across the street from the rock 'n' roll Wythe Hotel in Williamsburg is a design studio, Kinfolk, which also serves as a coffee house during the day. At night the handcrafted, garage-like space morphs into an ultracool bar, lounge and restaurant called Aska. Reservations for the $65 six-course tasting menu are available only online Sunday through Thursday. Fridays and Saturdays it's more of a walk-in affair where you can order from the bar menu, a roster of modern Scandinavian dishes that change daily and are closely in tune with the season. The Swedish chef Fredrik Berselius is one to watch and put your trust in, whether it's a special hot dog, herring, smoked shrimp or a potato dumpling stuffed with pork belly and cabbage—all of it exquisitely arranged on custom plates from a local potter.
