Sonny's Rådhusstræde cafe is a bright central Copenhagen stop for La Cabra coffee, breakfast, lunch, and a small backyard just off Nytorv. It is compact rather than formal, so the best visit is a coffee and something to eat, not a drawn-out tasting session.
Sonny is not a sprawling chain. The Rådhusstræde room is the one to know first, but the Frederiksberg Allé address gives the same idea a more residential register. That keeps the brand feeling like a small Copenhagen network rather than a polished concept with no local anchor.
Coffee
Coffee is built around La Cabra, which gives the menu a clean, serious backbone. Sonny's house blend, rotating coffees, batch brew, and espresso keep the cup lively even when you are there mainly for breakfast. The coffee side is not loud, but it is not casual either.
Filter
Filter is part of the offer, just not the headline. Weekly batch brew and rotating lots give the cafe a slower lane for people who want something more lucid than a default milk drink, and the La Cabra link keeps the coffee side grounded in proper specialty standards rather than lifestyle branding.
Food
Food is the stronger reason to stay. Sonny makes breakfast and lunch, keeps cakes in-house through its micro-bakery, and folds in rye breads, salads, rugbrød sandwiches, and a menu that bends toward the season instead of sprawl. The kitchen is not large, so the edit is tight, but that is also what keeps the place focused.
Service & Room
Service feels local and unfussy rather than performative. The room works best as a daytime stop for breakfast or lunch, with enough warmth to invite a second coffee and enough pressure around peak hours to make a reservation sensible. It is strongest when the weather is good and the backyard earns its keep.
Why Filter Notes shortlisted Sonny
Sonny is shortlisted because it gives central Copenhagen a cafe that does several things well at once: real coffee, proper daytime food, and a room with enough atmosphere to feel memorable without trying too hard. If you want one Sonny, Rådhusstræde is the place to start, then Frederiksberg Allé if you want the same idea in a quieter street setting.
