Failte Ireland's finalised guidelines will allow people an hour and 45 minutes in pubs that serve food, once they reopen from June 29th.
There will be two hours between each booking - with 15 minutes set aside for cleaning up after each group.
The social distancing guidelines will be relaxed for the sector, with one metre allowed where the two metre requirement isn't possible.
Contact details of the person who books the table will be held by the bar for contact tracing purposes - with clock-in services strictly followed throughout opening.
The guidelines say customers must be seated apart from using the toilet, paying and leaving - while there will be regular public health advice announcements during each sitting.
Carverys and buffets will be allowed - only with social distancing and with Perspex between the customer and the server.
