Turnover and profit at Côte Restaurants have both surged in its last financial year, to 28 July 2013.
The company, founded by Andy Bassadone and Chris Benians, and sold in September last year for £100m to private equity firm CBPE, saw its turnover for the period rise by more than 30% to £64.7m.
Meanwhile, adjusted EBITDA rose by 28% to £12.8m.
The company opened a further 11 restaurants over the period, taking it to 43 sites by the end of the financial year.
Côte, which was founded in 2007, established a name for itself by serving simple, freshly prepared French food at reasonable prices.
New owner CBPE has indicated that it wants to grow the business significantly and has given its full support to Côte's current management team, led by Harald Samuelsson and Alex Scrimgeour.
