Conor McGregor's mother and sister were among the many customers to try out the UFC star's pub this week.
Margaret McGregor and her daughter Erin were pictured at The Black Forge Inn in Dublin, with the Notorious' sister sharing a snap of the pair on Instagram.
The pub swung open its doors last Monday after undergoing a major refurbishment, which former two-weight champion McGregor paid for.
The 33-year-old purchased the bar last year and is reported to have forked out €1 million on a makeover of the venue.
Sharing a picture on Instagram, Erin commented: "My mamma @theblackforgeinn #mam#family#support."
The Black Forge Inn opened for the first time on Monday as Covid-19 restrictions were eased and indoor dining was allowed to reopen for those who are vaccinated or recently recovered.
The August Bank Holiday will mark the first weekend that the boozer is open to the public since it was taken over by the UFC star.
And a number of personal controversies do not seem to have affected the popularity of McGregor's new business, which is currently fully booked for all but a few early afternoon slots throughout the weekend.
Earlier this week McGregor took time out from mingling with Justin Bieber to praise staff for an "amazing" first day of opening.
The Black Forge Inn shared a picture on its Instagram page of three staff members hailing the "incredible" first day of service.
The image was captioned: "What an amazing day here at @theblackforgeinn , we would like to thank all of our old customers for coming back and supporting us as per usual, such amazing loyalty.
"To all the new faces that joined us today we can't wait to see you again and turn you into regulars.
"This is only the beginning for The Black Forge Inn. We have so many world class experiences to bring to Dublin Twelve.
"To the entire team, well done on an incredible first day of service. Tomorrow we do it all again. Sláinte."
Pub owner McGregor was quick to share his appreciation for his employees, responding by commending the "excellent work" of the team.
The Notorious is currently basking in the LA sunshine with his fiancée Dee Devlin and children Conor Jr, Croia and Rian.
