TGI Friday’s UK, the Electra Partners-backed, Karen Forrester-led group, has reported a 10% rise in total sales over the course of 2015 so far, with profits up over 16%, which it it said will increase over the final three months of the year.

The trading update came as the group also announced it would invest £3.5m in refitting the former Yates site in Leicester Square it acquired earlier this year, which will become its new UK and global flagship site, its 70th in the UK when it opens in November.

It will feature 260 internal and 60 external covers, as well as create 150 new jobs.

In addition to the Leicester Square opening, the brand is continuing to grow the Fridays footprint in the UK, with four more restaurants to open in 2015, and another eight in 2016.

The Leicester Square restaurant will also include an open kitchen and a large four-sided standalone bar, which will be the focal point of the restaurant.

Forrester said: “We’re incredibly excited to be expanding the ever-increasing Fridays family, and opening our flagship store in London’s vibrant Leicester Square. Well known as the UK’s centre for entertainment and fun, we’ll fit in perfectly.

“This landmark opening comes at an important time for the brand this year, which has gone from strength to strength, including being named the Sunday Times Best Big Company to Work for in the UK. It also represents a new era for Fridays as we turn 30 next year; the Leicester Square restaurant will set new UK and international guest experience and sales records from its opening, and we’re continuing to explore similar sites around the country that’ll strengthen this position.”

Bill Priestley, partner at Electra Partners, said: “We’re delighted to have secured this prime Fridays site, as we seek to develop and implement the company’s ambitious growth plans. This adds to the huge pipeline of new stores coming up both this year and into 2016, with hundreds of new jobs being created up and down the country. We’re really excited about what the future holds for Fridays, and can’t wait for the doors to open at its new restaurant in Leicester Square.”
