Restaurant Schønnemann (Copenhagen)
Founded in 1877 at Hauser Plads, Schønnemann remains the purist benchmark. Waitstaff in white aprons guide diners through over 100 sandwich variations. The house specialty—spiced curried herring with hard-boiled eggs and crisp onions—preserves 19th-century preservation methods alongside caraway-rich snaps.
