Hamburger brand Byron, and brasserie Brown's, are set to open restaurants in Liverpool ONE.
Byron has taken 3,894 sq ft and Brown's has taken 6,444 sq ft of the former Zavvi unit on Paradise Place.
For Byron, Liverpool ONE will be the brand's first restaurant in the North West. Brown's will be a new addition for Liverpool, having already opened in Manchester.
Located side by side between John Lewis and Harvey Nichols' recently opened Beauty Bazaar, both restaurants will open in spring.
Miles Dunnett, head of asset management, Grosvenor Liverpool Fund, said: "Byron and Brown's are fantastic additions to Liverpool ONE's line-up of leading dining brands. They provide even more choice, enhance Liverpool ONE's premium offer, and further increase its appeal for visitors living in the expanding outer catchment."
Tom Byng, founder of Byron, added: "As the starting point for our growth in the north of the country, Liverpool ONE is perfect. Byron will be in very good company."
Liverpool ONE claims sales were up by 7% over the Christmas period, compared to the same time last year, and 5% for the year as a whole versus 2011. It experienced its busiest ever day on 1 December 2012, with 172,000 people visiting.
Footfall for last year is claimed to have exceeded 26m for the first time, as growth for the year outperformed Experian's national benchmark.
Cushman & Wakefield and Tushingham Moore acted on behalf of Liverpool ONE.
