The company which operates the Bierkeller Entertainment Complex is reassuring customers that its Birmingham site will remain open for business as usual despite the owners going into administration.
The Broad Street centre cost £2 million when it opened in December 2016 with three destinations under one roof.
They included the Bierkeller itself, as well as the family restaurant Around The World (ATW) and Shooter's Sports Bar which has a large screen for major sporting events.
Burning Night Limited, which owns the companies which in turn own Bierkellers in cities around the country, announced it was ceasing trading this month after experiencing cashflow issues.
A Bierkeller Entertainment Complex at Cardiff’s Millennium Statium has closed after its future became unsustainable.
But the other bars and restaurants in Leeds, Manchester, Liverpool, Birmingham and Nottingham have been unaffected by the decision.
The company says that means all jobs and all customer bookings are secure.
Leeds also has a new concept called Smokin’ Bar & Kitchen, which opened at the end of 2017.
The company has more than 500 employees nationwide and annual revenue of more than £25 million.
All venues are said to be taking increased bookings for Christmas party packages.
A spokesman for BEC said: “Although we regrettably took the decision to close our Cardiff site, it has always been our priority to safeguard the other sites and keep them operating as usual.
“Both the company that owns the lease and the operating company of the Bierkeller Entertainment Complexes in the five other cities are trading as normal.
“We understand that customers may be concerned, especially if they’re planning to celebrate Christmas with us.
"But we want to assure them that they have no need to worry.
“Our Christmas bookings are stronger than ever and we’re looking forward to a very busy few months.”
The lower end of Broad Street is currently closed to facilitate the building of the new Midland Metro Tram extension - a four-year project to link New Street in the city centre with Five Ways.
Traffic diversions are in place, with Paradise Queensway currently forecast to be closed until 'summer 2018'.
