Melbourne start-up Mr Yum launched in 2019 with an app to try to avert food envy – a visual menu that lets you look at photos of each dish before making your order.

Then last year it introduced a home-delivery service with a 4.5 per cent commissions instead of the usual 30 to 35 per cent charged by some operators, and a directory for Melburnians looking for dinner within five kilometres of their home.

Now it has introduced a new feature that allows customers to set up a restaurant or bar tab, order food and drinks, and then pay for it through the app. “This year, Tabs will mean guests can spend less time lining up at the bar or squabbling over a bill at the end of the night, and more time enjoying food and drinks with friends,” CEO and co-founder Kim Teo said in a statement.

“Taking an order and taking payment can be some of the most administrative and time-consuming parts of a wait staff member's job, so if they didn’t have to do any of the admin their job would be just to be hospitable and create a meaningful experience for guests.”

Tabs is available at all Mr Yum restaurant, bar, cafe and pub partners, which numbers nearly 650 across Australia. In Melbourne that includes Dodee Paidang, Entrecote and Up In Smoke, and in Sydney The Grounds of Alexandria, The Duke of Enmore, The London and the Lord Dudley. In Brisbane participating venues include Darling & Co, in Adelaide there's Burger Republic; and in Perth Wolf Lane and Sweetwater Rooftop Bar.

Tab owners can share their tabs with friends through a unique link, allowing everyone to order from their own device and charge it all to one card. All cards are pre-authorised, so venues won’t have to chase up payments at the end of the night.
