The French-inspired chain has also launched a new in-house butchery and development kitchen.
In its latest financial statement, the 84-strong group announced a turnover of £72.7m for the year ended September 2021, with adjusted EBITDA of £0.3m, reflecting pandemic-related disruptions through the year.
Like-for-like (lfl) turnover was up 7.6% on 2019 for the period from reopening, from 17 May 2021 onwards.
It further reported that administration of the old Côte business was successfully closed, with key assets secured. Côte was acquired out of administration by Partners Group for £55m in September 2020.
The group also plans to evolve and innovate its menu in the coming months to reflect modern French cuisine.
Exec chair Jane Holbrook said: “2020/21 was the beginning of an exciting new chapter for Côte, with significant incoming investment from new shareholders.
“Whilst the macro environment has become considerably more challenging in recent months, we have fantastic support from Partners Group and we continue to invest and make progress towards our long-term goal of making Côte an iconic brand.”
