High atop the Mayfair Hotel in the middle of downtown Adelaide, Hennessey is one of the city's new crew of rooftop bars. Named after the architect who designed this former insurance tower in 1934 (all gargoyles and art-deco vibes), it's a classy fit-out but surprisingly un-snooty, with drink prices that won't ruin your holiday. And great views!
Access is via a sneaky elevator on the lower ground floor.
