Cuculainns of Cavan will take on Glenullin of Derry this weekend in the Ulster intermediate final.
Killian's Lodge owner Michael Farrelly described it as a "huge achievement" for a rural area like Mullagh.
Looking ahead to Sunday's final, the local business owner says when people are in good form everyone's spirit is lifted and that's what it's all about.
He described Mullagh as a place with "great community" spirit adding that Cuculainns is a major part of that.
Mr Farrelly says the hospitality sector has been "hit hard" over the last 12 months due to rising costs, with many businesses trying to finds ways of making it feasible to stay open which is a constant challenge.
Despite this, Michael says going through challenges makes highs like this weekend all worth it:
He said: "We're getting all excited about the Ulster Final, it's a huge achievement for the club. Hopefully, they'll do very well in it.
"We're 20 years there this year. It's great to be in the town, and it's great to have it there. If we haven't the support of the public, we're not open. We get great support locally," he added.
