About Mechanics Institute Bar

Perth hospitality veterans still regard Mechanics Institute as the blueprint for an open-air Northbridge rooftop hang. Duck through the rear alleyway and climb up to a split-level timber deck framing city skyline views. No stiff mixology posturing here—just bartenders pulling pints, pouring B Corp certified spirits, and stirring bespoke drinks matched to whatever you feel like drinking. The Campfire Paloma and a classic Old Fashioned set the baseline, backed by local craft taps. Regulars pair their rounds with hot chips, steamed dumplings, or burgers brought straight up from Flipside downstairs.

  • Rooftop Skyline Deck: An elevated split-level deck accessed via a rear laneway, offering sunset skyline views and relaxed open-air seating.
  • Tailored Mixology: Skilled bartenders craft custom off-menu drinks alongside signature pours and ethically sourced B Corp spirits.
  • Deckside Burgers & Bites: Patrons order dumplings, hot chips, and Flipside burgers ferried right up to the bar deck.

  • Direct Flipside Burgers Partnership

    Patrons enjoy fresh gourmet burgers and hot chips sourced straight from Flipside Burgers downstairs and delivered directly to their rooftop table.

    all food is from the flipside burgers underneath that it brought up to you while you have a drink.

Before you head over

Practical guidance on finding the hidden entrance, ordering custom drinks, and getting food delivered to your deck table.

  • Find the Laneway Entrance

    The bar is tucked away behind the block rather than directly on William Street; head down the rear laneway or secluded alleyway to locate the entrance and stairs up to the deck.

  • Order Off-Menu Cocktails

    Take advantage of the bartenders' deep spirit knowledge by asking for off-menu custom drinks or tailored flavor pairings suited specifically to your personal taste.

  • Order Burgers to the Deck

    Grab food seamlessly without leaving your table—order burgers and hot chips from Flipside Burgers downstairs and have them brought directly up to the rooftop deck.
