CG Restaurants & Bars has reported that its core Dirty Martini brand generated a 10.8% uplift in like-for-like sales in December.

The company said that sales at its new sites in Manchester and Leeds were also “exceptionally strong”, achieving a 28% uplift on budget.

It said that the three main factors driving the uplift in sales were a 21% increase in pre-booked sales, which accounted for 60% of total sales; exceptional trading in the week before Christmas, which saw eight out of 10 bars break sales records; and New Year’s Eve delivering a strong 12.7% like-for-like sales uplift.

Dirty Martini chief executive Scott Matthews said: “We’re delighted to announce an outstanding performance for Dirty Martini over the December period. Our new sites are outperforming expectations and existing sites continue to trade strongly, with Cardiff and Minories both delivering significant sales increases in their second year of trading as brand awareness increases. We are so pleased with how customers have responded to our latest Dirty Martini openings in Manchester and Leeds and look forward to opening our Birmingham site in April.”
