This was the speakeasy style tiki bar hidden behind the already excellent Archipelago DC tiki bar. Lost Island aimed to recreate a much more traditional Tiki escape from the city outside. Quiet, dark, completely removed from the U Street nightlife, the Lost Island had its own custom menu of classic and modern tiki drinks. A small bar area was separated from table seating. Access was by reservation only.

The Lost Island was temporarily closed during the pandemic, but never reopened. With the closing of parent bar Archipelago on 08/26/2023, the Lost Island is permanently closed.
