Bookings for outdoor tables soared, with some Dublin, Cork and Galway bistros saying that outdoor seating is now booked for prime Friday, Saturday and Sunday evening slots right up until the end of August.
Local councils and Fáilte Ireland have helped fund the development of outdoor hospitality facilities nationwide but officials say that capacity will fall short of likely demand, particularly at weekends, until indoor dining resumes next month.
However, Restaurants Association of Ireland chief executive Adrian Cummins again hit out at the delay in the reopening of indoor dining.
Indoor service for bars and restaurants can only resume from July 5 – something Mr Cummins said was “unjust and discriminatory”, with only one in five outlets capable of outdoor dining operations.
“The decision is baffling and without proper reasoning on medical or scientific grounds from Government, we have no choice but to take this as discrimination of standalone restaurants, cafes and gastro-pubs,” he said.
Publicans have said it is "great to be back" as bars, cafés and restaurants reopen for outdoor service..
Bars, restaurants and cafés can resume outdoor service as part of the latest lifting of Covid-19 restrictions.
Gyms, swimming pools and leisure centres can also reopen for the first time this year as part of the easing of other measures.
As a result, thousands of people across the country will be returning to work.
Local authorities in cities across the country, including Dublin, Cork and Galway, have pedestrianised a number of streets, along with installing additional public toilets and bins as part of efforts to facilitate an outdoor focused summer.
However, people are still being urged to continue adhering to the public health guidelines such as social distancing and avoiding crowds.
Taoiseach Micheál Martin said today was a "very significant day for pubs and restaurants".
In a video posted on Twitter, he said this "illustrates the continuing progress" being made to reopen society and the Irish economy.
