Spent a couple of hours outside this bar, in the late October sunshine. Just had a couple of drinks outside and didn't dine here this time. Bar service was efficient and the waiter was frienly. Drinks were as expected, cold and refreshing lol. Large bar in St Mary's Street in the middle of the city centre. There were about 8... More

Had many a good evening in this pub. Always a good band playing on friday nights. Ordered a Brains bitter and got a pint of vinegar, i was eventually given an alternative - Brains SA which was fine. The bar man looked at the glass and said "it's not cloudy" then left the glass on the bar, a few moments... More

I visit oneills quite often, always impressed with the food! The prices are good for the big portions you get, food is always really tasty and of good quality! Service okay but could be better, always seems like there's not enough people serving food.

Me and my girlfriend went in for a drink whilst waiting for a dining table elsewhere and the atmosphere was great, a very popular night life pub... We then wanted to find somewhere to eat so went back on a Sunday when the football was on and the atmosphere was great again, it wasn't too loud and the food was... More

What can be said about O'Neill's - not quite average pub grub yet not quite the gastropub experience that's claimed or charged for. The pub has had a bit of a refurbishment since my last visit and the new seating is much more comfortable with tables at a decent height. The menu has been overhauled and the thing that drew...

Used to go here quite often for work lunches. They had a new menu in a while back and weeks later still haven't got used to it. At least I assume because since then serve times have been awful even when the place is quiet. More than once had to rush to eat it in order to get back to... More
