As Dublin's traditional pubs reach their 400th consecutive day shut, the Licensed Vintners Association is calling on the Government to allow all pubs to start providing outdoor service from 24 May.
Pubs across Ireland shut their doors on 15 March last year, and Dublin's so-called wet pubs have not opened since.
The LVA is encouraging Dublin publicans to contact their local politicians to seek clarity on the reopening of the sector.
Donall O'Keeffe, chief executive of the LVA, said traditional pubs have been hit particularly hard by the pandemic.
"Traditional pubs across the country have had it harder than other forms of hospitality and the traditional pubs in Dublin were even more marginalised as they haven't opened their doors for the last 400 days and counting," he said.
"As we reach this unfortunate milestone we are launching a call to action and urging all our members to contact their political representatives," he said.
"They should press for the reopening of the hospitality sector to begin with outdoor service for traditional pubs, gastropubs, restaurants and hotels from late May," he added.
With hotels expected to reopen in June, the LVA said it believes all forms of hospitality should be allowed to resume indoor service from that point - especially with the rollout of the vaccine due to have reached 80% of the adult population that month.
"We see no justifiable reason for any section of hospitality to be favoured over others.
"On the day Dublin's traditional pubs reach 400 consecutive days of closure the tiered treatment needs to end," Mr O'Keeffe said.
