The plaza opened in May last year and figures just filed by Supermac’s (Holdings) Ltd show revenues across the group rose 17% going from €79.9m to a record €93.3m.
The opening of the plaza off the M7 motorway between Limerick and Dublin involved the creation of 60 jobs and the fast-food firm had the boost in revenues as the business expanded, booking €21.49m in capital expenditure and financial investment during the year compared to €3.56m in 2013.
“It was a good year.
"The revenues aren’t all Supermacs and include revenues of two hotels,” said Supermacs founder Pat McDonagh.
“We are very happy with the way the Barack Obama Plaza has performed and it has received very good customer feedback.
"It is a well-established stop between Limerick and Dublin.”
Mr McDonagh confirmed six new outlets opened in 2015 with plans for a further five or six next year.
However, pre-tax profits at the group last year declined by 4% going from €7.1m to €6.95m as a result of an exceptional cost of €2.68m relating to the write- off of loans to connected firms.
