It opened in 1969 and later became the first outdoor pavement cafe in Canberra. It is one of the oldest and best known cafes in Canberra and one of the first European-style cafes in Australia. It has both outdoor and indoor dining areas.
The cafe was established by Augustin 'Gus' Petersilka (1919–1994) who emigrated to Australia from Austria in 1951, and arrived in Canberra in 1962. Petersilka had difficulties with introducing this new style of dining to Canberra as it was against the regulations of the time for people to sit outside in a cafe or restaurant and he had several well-publicised clashes with bureaucrats.
A plaque on the pavement outside Gus's cafe marks the occasion of Gus Petersilka being made the Canberran of the Year for 1978. It reads:
Petersilka has additionally been commemorated with a street named after him in the Canberra district of Gungahlin.
