The accounts for Orsen Ltd’s pre-tax profits almost doubled to €1.88m last year.
Its entertainment business led by Mr McKillen and Matt Ryan has expanded rapidly in recent years.
The accounts for Orsen include the revenues from Wagamama restaurants, as well as the revenues at the Everleigh Garden nightclub on Dublin’s Harcourt St and the Workman’s Club in Temple Bar, which is adjacent to the Clarence Hotel.
Orsen includes the Press Up Entertainment firm where revenues increased 36% to €42.9m.
A spokeswoman for Press Up Entertainment said it was “very happy with the overall performance of the group”.
The key factor in the revenue increase for 2015 was due to The Dean Hotel’s first full year of trading, the spokeswoman said. The hotel opened in November 2014.
“It is difficult to foretell whether we will exceed profits this year, as it is the final third of each year that is the busiest across the group,” she said.
Mr McKillen and Mr Ryan have plans to expand its WowBurger outlet; open a boutique hotel in Ranelagh for which demolition of an existing building has started; open a hotel in North Wall Quay; plans for a new pub on Aungier Street; and open a boutique food market with two restaurants and a bar next door to The Clarence Hotel in Temple Bar.
It employs 1,090 people across the whole Orsen group, which includes the Bison Bar, the Peruke & Periwig and Cleaver East.
The company made interest payments of €649,041.
Staff costs at the group increased from €10.83m to €13.5m, while the firm’s cash last year fell slightly from €895,861 to €815,520.
Total pay for directors increased from €137,012 in 2014 to €150,000 last year.
The accounts show that at the end of last year, the group owed €777,902 to Paddy McKillen Snr and €289,968 to Paddy McKillen Jnr.
