Customers will also need to order a 'substantial' meal over €9.
People may only be allowed spend 90 minutes in restaurants and pubs that serve food when they reopen at the end of the month.
It’s understood it will be part of new measures that will allow the two metre social distancing rule to be reduced to one in certain circumstances.
Customers will also have to pre-book and spend at least nine euro on a substantial meal.
Padraig Cribben from the Vintners Federation of Ireland believes these measures would be restrictive but workable.
''Ninety-minutes seems some what restrictive if someone wants to have a full meal, but publicans are used to monitoring situations like this,'' he said.
Under the governments road-map for reopening the country, restaurants providing on-premises food and beverages can reopen on June 29th.
However, they must comply with social distancing and strict cleaning protocols.
