Flanagan's Bar & Restaurant

You'll find this spot holding down the fort on Upper O'Connell Street, doing the kind of reliable Irish cooking that keeps both tourists and locals coming back. The dining room feels properly old-school Dublin – dark wood, cosy corners, and the sort of atmosphere where you can nurse a pint over lunch or bring your parents for Sunday dinner. The menu covers all the bases from a proper Irish breakfast through to evening mains, with generous portions that won't leave you hungry. It's the sort of place where you know what you're getting – solid comfort food without any fuss or pretension. The location makes it handy for a bite before or after wandering around the city centre, and the consistent opening hours mean you can rely on them when other spots have called it a day.
