And in the hot weather, Belfast workers tend to congregate on the benches and grass to munch their sandwiches and soak in a little sunshine before heading back to the afternoon grindstone.
But today, Belfast City Hall is opening its gates between 11am and 7pm to citizens and visitors for a grand Picnic on the Lawn. There'll be bluegrass, Irish trad, Chinese dancing, circus acts, and the Really Rubbish Orchestra (recycled instruments) will be playing too. (See the full programme for details.)
To quote the Lord Mayor Pat McCarthy:
"The City Hall belongs to the people of Belfast - all the people of Belfast - and the centenary events have been designed to show the building off to the people who own it."And if you can't make it along - or the rain puts you off - you can monitor the floods (sic) of people pouring through the gates on the City Hall webcam.
