No more than 6 people are allowed at a table in restaurants and cafes from now on and a record must be kept of what customers order.
Failte Ireland has updated its guidelines for the industry to stop the spread of Covid-19.
There should be a maximum of 6 people from three separate households at a table in a cafe or restaurant from now on.
Businesses and services must keep a record of what each person orders and the time and date of customers' arrival must be noted.
The name and contact details of one person per party must be recorded for both walk-ins and booking and all details will be kept on file for 28 days.
When it comes to drinks, all straws must be individually wrapped and embellishment or decoration of glasses like cocktail umbrellas should be minimised.
The new guidelines come as the Dail debates new powers for Gardai to shut down pubs and restaurants who aren't complying.
