The Pitch

Our Take on Mechanics Institute

Mechanics Institute sits on top of 222 William St, and the trick is getting in: you walk around to the rear laneway off James Street and climb the stairs. The City Lane wrote up that hunt years ago and people still miss the door weekly, which Tripadvisor reviewers confirm with some pride.

Once you land, it is one of the easiest rooms in Perth. A split level small bar, a rooftop terrace looking at the city skyline, and a team that has won national awards for running it.

The Room

Reading the Room

The terrace is the draw, brick walled and set with long communal timber tables, now under a retractable roof that keeps winter sessions alive. The Rooftop Guide calls the setup urban basic, which reads about right and is exactly the charm.

Inside runs darker and closer, better for the colder months or a conversation you actually want to finish.

The Drinks

What to Order First

01
Whatever leads the daily board
The cocktail board changes every day and is where the bartenders show off. Tell them a spirit and a mood and take the recommendation.
02
A properly made classic
The venue won Best Small Bar and Best Bar Manager at the Australian Bartender Magazine Awards, so a Negroni or a daiquiri here lands the way the recipe intended.
03
A burger sent up from Flipside
The burger bar downstairs delivers to your table at Mechanics. Order at the bar, hold your table, and the kitchen does the climbing.
Crowd and Vibe

Who Shows Up, and When

Gallery and museum people cross William Street after work, and the pre show crowd holds the terrace before gigs at the Northbridge venues. Weekends fill the rooftop by late afternoon.

Yelp reviewers single out the staff as the reason they return, funny and informative being the recurring phrasing. Go on a weekday if you want a table without a wait.
