Gardai say drinking alcohol in outdoor seating areas is not allowed under licensing laws.
They say places selling food or drinks can only do so on a takeaway basis or for consumption off the premises.
The comment comes almost two weeks after outdoor dining reopened here.
In a statement, Gardai say while local authorities can permit additional seating space outside, these spaces are not covered for alcohol consumption by the licence issued by the District Court.
They say they will continue to work with all stakeholders with the reopening of the economy and society.
