The group, owned by Russel and Juliette Joffe and Andrew Jacobs, has agreed a new 25-year lease on the former Tortellini restaurant adjacent to Cote in the town.
The acquisition follows the opening of the group’s first Scottish restaurant at the Union Square shopping centre in Aberdeen last month.
Giraffe Restaurants has been conducting a rapid and targeted expansion plan with the help of financial backing from Luke Johnson and venture capitalist 3i.
At the time of its Aberdeen opening, the group said it planned to open a further four or five sites by January 2011.
Brandon Elmon, director at Davis Coffer Lyons who advised on the deal, said: “Giraffe is a fantastic concept at the very heart of what consumers are after today. It has been able to grow significantly over the past ten years, we are delighted to be helping with its continuing expansion.”
