There are plans to put in a 250 seat restaurant in the basement of Cineworld on Parnell Street.
UK company Wings International is looking to open its first buffet-style eatery in Ireland at the theatre complex.
The cinema isn't just the busiest in Dublin, it's one of the five most bustling in the UK and Ireland.
Cineworld has told Dublin City Council that the basement of the complex has been vacant for years.
