O'Neills in Cardiff

O’Neill’s on St Mary Street is a place where the only thing stronger than the Guinness is the scent of spilled pints on the floor. It’s the kind of pub where the Wi-Fi signal is as spotty as the bar stools, but honestly, you’re better off chatting with the locals who seem to have mastered the art of *small talk with a side of banter*. The menu? Think comfort food with an Irish twist—because nothing says "I'm having a great time" like a plate of nachos that could double as a small country. The vibe is a mix of "we’ve been here since 1997" and "I’m just here to watch the match", which is basically code for "everyone knows your name but will still ask for your ID." On a busy night, getting a drink can be like a game of musical chairs, except the music is the sound of *someone else’s elbow in your ribs*. But hey, the staff are fast, friendly, and won't judge you when you order your fourth round. If you’re looking for a cozy, chaotic, and unashamedly fun pub experience, O'Neill’s is your place. Just remember to keep an eye on your coat—it’s a pub, not a wardrobe!

We went here for breakfast on a Sunday morning, and we both ordered the hearty breakfast. There are 3 sizes of breakfast, and we chose the middle size, but I wish I had gone for the small. The portions are very generous, and the food was lovely. It is good value. We had to move on to somewhere else for a coffee due to their coffee machine not working, but when next in Cardiff, we will definitely be back for breakfast. Thank you!

Serve i soliti piatti standardizzati. Nulla di caratteristico e memorabile. Qualità discreta prezzo medio. Personale cortese serviIo eccezionalmente spartano.

Bar sympa pas loin du marché de Cardiff. La place est super animée. Une église arbore également la rue. Il est bien de prendre un verre en terrasse car beaucoup plus agréable.

We visited this place for food while we were visiting Cardiff I had the kebab which was lovely and very well priced my wife had a cheese and pickle baguette which was also nice the staff was very friendly the place was welcoming and the best bit was they allow dogs definitely be visiting again

Advacado on toasted muffin with tomatoes & mushroom. Perfect light breakfast. Manager very accommodating & helpful.

Went to watch rugby for super saturday Wales vs Italy was ok but volume of music was to loud before and during intervals couldn't here my friend right next to me because of the volume. Also was unimpressed with intermittent audio and when they played music over the top of Scottish national anthem for Scotland Vs Ireland game was further disappointed that I heard more of the Aldi advert than than national anthem. Also disappointed in the fact that food options limited due to refit in 2 weeks I understand need to reduce stock but not tailoring menu or reducing it to not give false advertisement of meals would be appreciated.

Pub sympa, assez grand (trop pour certains, moins intimiste), la nourriture est pas mal, dans la moyenne pour un pub. Pensez à réserver s'il y a des évènements sur le week-end (6 nations dans notre cas)

Robbie, cam and Lewis, an absolute credit to the team, made us feel so welcome and incredible hosting from the trilogy:) ❤️❤️

Six Nations. This has always been our go to pub. This time though the music was terrible. Dance music with chipmunk vocalists. No Tom Jones, Stereophonics , or any sing along songs once the match had finished. People leaving to go elsewhere. Small queue to get in, in comparison to other pubs. Ladies toilet....no toilet paper despite highlighting this to staff twice. Disappointed.

Love this place - especially for the up and coming 6 Nations - Bsr staff are mega friendly and Amanda and the Crew never let us down The Entertsinment spot on too - Best Ever night there was the night before Wales v Ireland ' never knew I could do the Irish Jigs.Fantsstic Atmoshere but won't mention the result.😃😃.

Visited on a quiet Monday night in a small group of lads. Food was banging, the bar team recommended Tapas and Pizzas and they didn't disappoint, we were stuffed! Great selection of beers & sport on huge TVs. Shout out to the manager, Jack, Great service all evening & good recommendations of where to go next. A top night!

visited her on the weekend was served by amanda she was very helpful and friendly! lovely food to ⭐️⭐️⭐️⭐️⭐️

Lovely place. I enjoy coming in here for the food and drinks. Amanda always gives us exceptional service on any our visits and always puts a smile on our faces. Thank you Amanda!!

Outstanding food, great service by Amanda, made us feel very welcomed, would highly recommend to anyone who was looking to come here!!

We come here quite regular and the service from Amanda is always outstanding. She goes above and beyond for us! Thanks will see you again soon 👍

Amanda was so friendly and chatty, we love this pub and always make the effort to visit when in the center.

Good food ,lovely staff. Clean and welcoming vennue with a wide range of live music and sports on display . Location is perfect

Robbie was such a good waiter! Very attentive and friendly! 5 star service would highly recommend this place!

Fabulous service from Kayleigh and Tom. Lovely spot for food and some great music on. It is really good at night with a lively atmosphere.

Great service for Meg, very friendly staff. Served with a smile and very polite. Will definitely recommend and will be coming back.

Had lunch here after a golden retriever Xmas party I had a jerk chicken flat bread which came with chips and coleslaw which was delicious my wife had a vegan pizza which she enjoyed the staff was very friendly and helpful the food arrived promptly and very reasonable priced and best of all you could take your dogs in definitely will be visiting again

Ordered 4 meal and portion of chips with drinks. Meals arrived but portion of chip didn't, so we asked a server waited, asked another server waited again. By this time we had finished the meals and nobody bothered to bring the potion of chips which we paid for.

Watch a young man and his partner enjoining the Monday night football (Chelsea v spurs) and only to be asked to leave the establishment, as he enjoyed his team score a goal to equalise 1-1. He tapped the table with enjoyment. The two lady’s asked them to leave but in my eyes they both were absolutely fine and the two lady’s didn’t really understand the passion of sport. The young couple were not causing any problems and was invited into the pub to watch the live sport. I do feel O’Neils was a better than this . Shame as Cardiff is a great place but much better pubs than this !!!!!

We travelled to Cardiff whilst on holiday and popped into this pub for a bite to eat with our assistance dog. Turns out it’s a dog friendly pub anyway but wow they were so lovely with our pupstar. I can’t go into details in case they get into trouble and I wouldn’t want to open floodgates of expectations but they are simply the best place we have ever been to in relation to our little dachshund assistance dog who they all fell in love with. Thank you so so much!! Oh and the food was delicious too from everyone who ate here 😉

Well visited here often. Never complain. The grill was broken, we ordered a Gammon and a char grilled chicken breast. As the grill was broken , I was having thoughts to go eat else where. The guy taking my order said it could be cooked...

Don't go in with a group of you because you get refused we had 12 guys and the guys at the door said we was to drunk and we just got to Wales. There's no reason for this I think it's because we aren't woman......

You can go for a beer at O'Neilss but stay away from the food. We had 3 tapas for 13 £ and they were all awfull. Old squid in old flkavour cooked in old oil - and so on. There is nice seating oiutside and...

What a dump 8.30 on a Friday night Tables outside not cleared and all the staff standing around talking ! The proof is on the photo !

Arranged to meet friends here 5 O'clock on a Saturday afternoon and the sound system is so loud, can't even hold a conversation. Come O'Neil get a grip, save it for later on in the evening

I've visited this pub before on trips to Cardiff and usually everything is fine but on this occasion even though I asked for a bottle of the house red (£12-£13), I was automatically charged for the dearest wine (£17.50). I wasn't offered a choice. It...

Rugby weekend great atmosphere in the pub friendly staff and a great over all experience This is the place to be on a weekend in Cardiff

Came for the rugby and the atmosphere was incredible, guiness was poured correctly and staff were lovely

Amazing day watching the 6nations. Plenty of screens for viewing so everyone is comfortable watching :)

This spot I'd a lovely and very classic dot to be amazing for birthdays and Amazing staff I would very much recommend

Came for the football. The server (Jack) was kind enough to split the games over multiple screens for us. Will definitely be coming back to watch the Champions League next week.

Food (tapas) was ok in Cardiff O’Neill’s - but after that all went downhill - ftom bar staff who barked at customers (to wait a minute) to barstaff who poured guiness in one hit ( you’d be shot in Ireland for thAt ) to toilets...

Went to O'Neill's this morning for breakfast. Quite quiet considering Cardiff were playing Millwall and Spoons was rammed. Breakfast was great, decent value, staff courteous and professional. Recommended.

Wonderful atmosphere excellent food at this popular Cardiff Pub. Had great service from Tom H who helped us with ordering our meal - I’m never any good at using an app! Thank you Tom

A very pleasant member of staff served us today she exceptionally polite and very happy .The member of staff was Amanda .

O’Neills was nice. Nice food, big portions, good value for me as well. The pints however were disappointing being so unorganised that both of there Carling taps were empty. I had to settle for a poisonous Coorse to get the drink deal with my food...

A short visit to Cardiff and we found this place. The atmosphere was great and the food and drinks very reasonable. The service was fantastic, with wonderful friendly staff. A great experience.

Had the most amazing time at O’Neill’s!! Came here for my friends hen party and had the best atomosphere! Much come here! Xx

You want a cocktail, they have a great selection of the classics! I went for a strawberry daiquiri and it was perfect! There were a lot of drinks being made and they all looked amazing. Big shout out to Cam who served us

Bar manager with purple hair was extremely rude- I and my friends will not be returning. I took an ‘alcoholic drink’ back as it tasted like water and she was very rude and did not offer to sort the issue.

RAMMSTEIN We went before the RAMMSTEIN gig in cardiff and it was great atmosphere. Pricey but lots of music and tailored to the day. The guy on the laptop looked stressed out as he didn’t know what to play next! But overall good enough for...

Have been to O'Neills a few times and there's always a great atmosphere - especially on game days! Staff are also always really friendly and helpful.

First of all the food (korean style wings, philly cheese steak and a chocolate brownie) was delicious and full of flavour but the joy simply ends there. I came to the pub with the intention of watching the Scotland vs Denmark match. The staff refused...

Went for breakfast on a Sunday with 5 friends. We each ordered separately at the bar and overall ordered 5 full Irish breakfasts and 1 bacon bap. The food took around 30 minutes to arrive, which was a slight annoyance but they could be forgiven...

Cannot praise the staff of O’Neills on St Mary St. we reserved an area to have drinks with friends and family on the evening of Oct 16th 2021. We requested the private bar to be opened, therefore our guests didn’t need to queue at the...

Everything sticky! The bar,.tables and floor were disgusting. Staff inattentive and unmotivated. Toilets dirty and smelly and no soap in the dispensers, the 'Manager' seems not to care less, rude and no customer service skills whatsoever! Shame as this used to be a favourite place...

Totally obnoxious door staff, beer only ok Do yourself a favour and spend your money somewhere else.

Called in here a few times for drinks and food. The breakfast was fantastic, really tasty, just what we needed after a night on the town. Night time in the bar was great. live band on a Friday Night which were really good. Sat night...

Me and my friends visited Cardiff and encountered many different bars and restaurants down an architecturally interesting street called St. Mary’s. O’Neill’s, however, was my favourite one and would 100% recommend it. We were seated and served in no time and the staff catered to...

Very well set up, Covid safe! Staff very friendly and helpful! Dealt with any issues from any pub goers not following the guidelines! Enjoyed a pint or 2 watching the football! We will be returning!

The restaurant provided a huge screen to watch sport, which was pretty comfortable to watch football. Also, bartender and manager were quite helpful, which helped me enjoy the evening even more!
