Freshly Chopped claims the potential closure of its Grafton Street outlet could threaten jobs across the company.
Planning chiefs are considering whether the salad bar chain can remain at the location.
It's after Dublin City Council refused planning permission for its Grafton Street branch.
The salad bar didn't seek permission before it opened up an outlet at the Trinity end of the street.
In 2013 the city council introduced rules around what kind of businesses can set up shop on Grafton Street.
It would ban any future fast food, mobile phone shops, bookies and newsagents among other businesses.
Freshly Chopped claims the closing of their deli would threaten the jobs of 600 staff across 45 other outlets.
