Residents in Killarney, Co Kerry say traffic from its McDonald's is causing 'havoc' for them.
The restaurant, which also offers a drive-thru, is said to be increasingly popular since the pandemic began.
Killarney Mayor Marie Moloney says this seems to peak at certain times of day, mostly in the evenings after school.
She told Lunchtime Live more people are using it the drive-thru, and this is a problem.
"I guess it's the result of the pandemic, it's a side effect of the pandemic - because a lot of people now are using the drive-thru services of McDonald's.
"They don't want to go in, the numbers are high, they want to just get a drive-thru take away - and I can understand that."
But she says planning has not been done to cope with larger traffic volumes in the residential area.
"So they are queuing on one side of the road: the road now leads to McDonald's and to at least five residential estates at the back of McDonald's.
"So they're queueing all on the left-hand side of the road as you go in, and then what's happening is people are parking on the right-hand side.
"Up on the footpath and up on the double yellow lines.
"And it's causing havoc for the people who want to go into their homes".
She says she has concerns that emergency services might not be able to access the homes, if needed.
"They can't get in, the road is blocked, they have to sit and wait till someone comes out and moves their car.
"If we should need emergency services in there - such as the fire brigade or the ambulance - I'm afraid there would be problems getting into those estates".
'It's no reflection on McDonald's'
And she says she has raised this issue at council meetings for months, with hopes of a solution.
"I made a suggestion that the engineers would go to McDonald's and ask, would McDonald's work with them to take away part of the green area, put a filter lane going in.
"And that would mean that the people coming out of Killarney don't have to swing around the bend on be on the wrong side of the road.
"And on the other side... I think [bollards] may be the only solution to help the people that live up there in those estates.
"It's no reflection on McDonald's, McDonald's are there for a long time."
She hopes a decision around a filter lane will be reached by the time the local council meets again in a few weeks' time.
She also notes that McDonald's was there "a long time before some of the housing estates went in there".
