Named for Hamlet's castle in Elsinore, Kronborg is a modern smørrebrød luncheon cellar cast from a traditional mold: a low, bang-your-head doorway, beamed ceilings, plaster walls, tight tableclothed tables, and in good weather, outdoor seating. Tucked on a side street off the pedestrian shopping drag Strøget, it's all soothingly condusive to conversation and upscale lunching, and the ingredients are sourced to carry the weight of a classy lunch. Ingredients are fresh, the kitchen blends its own list of distinctive aquavit (in flavors as curious as dill and beech), and the desserts are gorgeously piled high. Menus are available in English. Make a reservation by email (reservation@restaurantkronborg.dk) or you're likely to be declined, because the Danes take their smørrebrød seriously.
