Dublin is expected to move to Level 3 of Covid-19 restrictions with some additional measures later today.
The Cabinet sub-committee will look at the advice from the National Public Health Emergency team which is expected to include a ban on indoor dining for restaurants and bars in the capital - which would be a step up from Level 3.
The restrictions will then be brought to all Ministers before an announcement this evening.
Moving to level 3 restrictions means that people won't be allowed to leave the county unless it's for work, education or other essential reasons.
The number of people attending weddings and funerals will be reduced to 25.
Religious services like mass will move online, and people will be advised to work from home.
The Restaurants Association of Ireland says thousands of people will be out of work at short notice this weekend if indoor dining is banned in Dublin.
The trade group says the 2,000 eateries in the capital will need a bailout if it goes ahead.
