They all received a zero rating in their most recent inspections, meaning urgent improvement is required.
Among the city's worst performers were Chinese restaurant Bar Red, which has since closed down, on Queen Square and the Peach and Pear Cafe in Hyde Park, which sells American-themed dishes.
Two Kirkstall takeaways, Kebabish Tandoori and King Dragon, received the lowest rating, as did chicken restaurant BFC in Burmantofts.

Pizza Pie in Bramley, Rashid Brothers on Roundhay Road and Anwar's Mini Market and Zak's, both in Woodhouse, were also given zero ratings by inspectors.
The majority were visited by Food Standards Agency teams in 2016.
Peach and Pear manager Shanwaz Iqbal told the Yorkshire Evening Post that he had agreed a second inspection with the FSA this month due to structural problems on the day of their visit.
Takeaways, cafes, restaurants and bars will soon be required to display their food hygiene certificates in full view of customers when new legislation comes into force.
Research by NFU Mutual revealed that 44 per cent of diners would refuse to eat in an outlet which had a rating of three stars or fewer.
Hospitality sector specialist Darren Seward said:
“Our report shows that when it comes to food safety customers have naturally high standards and that a ‘good’ score can no longer be seen as an aspiration but a minimum benchmark.
“It’s fantastic to see that 84 per cent of food outlets in West Yorkshire have a rating of good or very good and the industry as a whole is taking real pride in food hygiene, but imminent compulsory displays are destined to be a game changer for those businesses struggling to reach the top grades. In advance of legislation changes all business owners should prioritise their food hygiene plans and processes, acting now to ensure that they have considered all hygiene and paperwork aspects rated by their local authority including cleanliness, structure and confidence in management."
