O'Neill's in Cardiff

The venue very kindly let us use the upstairs space to host a pub quiz in honour of Ty Hafan for free. Thank you Ethan for looking after us!

O'Neill's: The pub where the Guinness flows as smoothly as the banter, and the hearty portions of food could probably feed a small village—assuming that village isn't too picky. From the moment you step in, it feels like you're either in an Irish village or a cozy, slightly chaotic living room of a long-lost friend. The staff are like family, if family was full of people who didn’t mind cracking a joke or two while serving you. And let’s talk about the food: If your stomach had a voice, it would be singing praises after a plate of their fish and chips. Crispy, golden, and practically begging for you to dip it in tartar sauce—this is comfort food at its finest. The drinks? Well, it’s O’Neill’s, so expect a pint of Guinness so perfectly poured, you might start wondering if the bartender is actually a wizard. The ambiance is a delightful mix of cozy and lively—like someone threw a traditional pub into a blender with a splash of good vibes. The only downside? You might leave with a food coma and a lighter wallet, but hey, that’s the price you pay for a night of laughter, food, and pints that come with a side of Irish charm. Would I recommend it? Absolutely—just make sure you’re hungry, thirsty, and prepared to leave with a smile on your face (and a bit of a food baby).

Most rude security staff I ever met. Arrived in Cardiff by bus from Bristol Airport and just wanted to have a beer and catch some livemusic before getting to bed at my hotel. Accused me of being to drunk to enter even if I didnt have a single drink before. I have always had great experiences in the UK befor but this was absolutely awful

Great service from the team and great food.

We watched a comedy show here that was very good and the atmosphere in the upstairs room was perfect. There was also a good band on downstairs. And a nice selection of drinks including cocktails.

Great atmosphere, friendly staff.

Very fun and such a good atmosphere

Bar man let us sample the wine before we ordered. Lovely atmosphere and good music.

Adam on the bar had great service! Definitely recommend O’neils anytime

nice food, was quiet when we went there which is unusual is lovely supervisor shame about the first guy that served us didn’t get his name, looked very unhappy in his job! work in customer service myself so know how first hand impressions count 😊 thanks lewis, for rectifying poor service!

First hand impressions to me are very important and unfortunately the first person to serve me in O'Neil today didn't leave a very good impression, but fortunately for him the food, company, drinks offer & supervisor made up for it thankyou very much Lewis!

Nice enough pub. Friendly staff. TVs are loud during the day though

Great for watching sport,good beer, only downside is that it is usually very busy

Felt very unsafe. Too scared for my own safety to return.

Enjoyed a fantastic breakfast. Quick service. Welcoming staff.

A football pub exactly as it should be. Good burger, with even better Guinness. Got a waiter who could pour Guinness properly. Good setup to watch the match and clean toilets

Good for those who want to dance and drink. It's a pity that the tables are dirty and no one even thought to come up and wipe it

Went there on a night out, with some German friends. Great pub, though I was disappointed to see the heads of the band Daft Punk, mounted in the gents toilets 😀 Otherwise, great place

We had a great time visiting Cardiff and dining here 😀

The Gammon was brilliant. Hit the spot. Would eat here again.

Really good food and service. Would come again!

Had the mac and cheese. Worth the extra toppings. However, was Small portion considering it was a additional topping. Food came in good time. it was very busy but the guy who served was run off his feet and maintained good service. This guy deserves a pay rise.

Great staff, good atmosphere. Good food!

We didn't eat here today however the service and atmosphere was value for money

Great and helpful service, food came extremely fast and well delivered. Will definitely be coming here again.

10 out of 10 all round amazing food and fantastic service :) Thank you

Early afternoon drink and some food, mix XL MIX Grill nniiccee.

Really good surface, did not ignore me

Out Saturday, really enjoy it one of the best nights out I’ve had in a while. The bald bartender made it a great atmosphere, he went above and beyond for the service we had. Will definitely be back and will be telling all friends and family about this lovely place. Thank you!

Fun, clean, fast serving on the busiest of times. Great time, great service.

Service was great! I would highly recommend this as a great spot for anyone.

Adam best Bar man in town thanks fab service

Staff amazing especially Adam who went above and beyond

Great for sports events, good selection of beer.

Just popped in at 6 pm on a Saturday night and place was already jumping! Just had a quick drink hence the no food ratings. Good selection of beers at City Centre prices.

Fav place every weekend to have a great time with friends and so many memories!

Wonderful bar staff. Really nice atmosphere and music.

Chilled atmosphere, helpful staff

Great atmosphere. Amazing service and tom was great. Will defintely come here again.

Memories of coming in here in 2009 and listening to a really great band whilst on holiday, seems only like yesterday while sitting in our favourite cosy seats. Still love visiting this establishment now thst we live in Cardiff.

Lost an item last night and the staff located it and handed it to me straight away thank you

Great bar! Great atmosphere! Loves my time here.

Amazing food and amazing service definitely going back

Great Overall! Brownies are scrumptious 😁

If I can't be in Ireland, this is next best. Great environment and selection.

Food was delicious and the service was fast.

Every time is a great time at oneills.

Tom you are a legend! Definitely coming back!

Loud and proud. Good beer selection. Not my bag but great for those who like loud music in the room.

One of my favourite post work sports to enjoy a cheap quality pint

A great place to meet up with friends watch sport. With great deals in the week with £3 a pint. Can not be beaten. A must on any Cardiff trip or a cheeky beer after work.

Eilir,Lee and Tom great service. Had a great time!

Lee, Tom and Eilir such sound bartenders. Great laugh. So chill. Love it. Big up. Bless up

Lee and Tom gave me perfect service. Made me a gonster. Bless up

Tom and Lee provide great service for drinks and are great workers to talk to.

Great service from Tom, Eilir and Lee, perfect pints and great guys to talk to.

Oneils is one of the best pubs for a night out in Cardiff, Eilir, Tom and Lee help provide a great atmosphere

This place is amazing, great customer service. Would 100% come here !!

Enjoyed my lunch here ,good staff and good food . The world’s best staff and chefs . From Lenny

Great place for a pint and a catch up. Bar team are on the ball!

Great atmosphere, great deals and great staff. Cannot recommend it enough ☝️ Sometimes i go here with a bag of cutlery and count “one spoon, two spoon, teaspoon” 🙈

We had to stop since my family's are O'Neill's and we loved the sausage and mash. Food was great and the beer was cold and delicious.

Great atmosphere and a good bar plus staff

Friendly and awesome atmosphere

Very good experience with kicking tunes,,, just (hate to sound old), but the music was too loud, as you could not have a conversation, even when you're shouting as loud as you could. I like the music loud,, but that's too loud & that's me saying that

I love o’neil’s because the prices aren’t bad and it’s always a great time. Liv’e music is so good and even the DJing is good.

Far too expensive these days. £6.80 for a ping or Madri.. £7.20 for a hazy Jane. Hard pass in furtie

The staff were so kind and helpful, we are not from the area and accidentally ordered to the incorrect o’Neil’s, the staff sorted us out within 5 minutes of getting to the right establishment without having to tell them what had happened! Amazing service would 100% come back

Food is very delicious and the stuff is friendly despite being quite busy with the lot of people spending time here. Unfortunately, sometimes it takes very long until tables are cleaned, so it can be hard to find a clean table. You order via a QR Code at the table and it doesn't take long until the food arrives.

Great food and atmosphere. Highly recommend

Nice pub with lots of options on tap. Great service and a nice breakfast

Came for a meal last night husband had hunters chicken I had fish and chips it was lovely freshly cooked and lovely and hot

Quick easy service, relaxed atmosphere

Jack was my server, very kind and inviting. Lovely selection of drinks. Top marks.

Server was a top bloke, great pub , lovely location, great vibe and drink!

Was very nice and tasty. Good experience

Lovely pub with a friendly atmosphere. Great live band's

Nice bar not far from Cardiff market. The place is super lively. A church also adorns the street. It's good to have a drink on the terrace because it's much more pleasant.

Had a gin and tonic. Hardly any gin in it... Less than half a small dose. When I asked if there was any gin in these I was told, "oh, did you want it double?"... Every half decent bar should know that a g&t should not be made single or double! Should be made like a decent g&t! Ah, about dinner, it took me the whole night to digest a scotch egg and a pie...

Great atmosphere, great food and service! Definitely recommend! X

Mason was brilliant, very helpful with finding Gluten free options to eat😄

Great service, put on the commentary for us in a slightly separate area so others wernt bothered by it.

Lovely friendly lady named amanda very helpful and happy

Fantastic day in Cardiff at O’Neill’s, good look good but didn’t try. Pints of Guinness poured correctly and tasted like smooth ice cream. Sports on multiple screens and even turned the commentary on for me in the game I was watching

Loads of screens and a great choice and variety of beers. Great sports bar

Popped into ONeils for the football, Amanda and Nils where very welcoming and helped with everything we needed

Lovely food and Lovely staff , Recommend a visit!!

Robbie and Lewis were wonderful to us and always made us feel welcome so we came in each day from Thursday to Sunday whilst we were here for the Bruce Sprinsteen concert! You are very lucky to have these amazing guys on your team - an absolute credit !

It seemed to be in Dublin. Great pub.
