O'Sullivan's Irish Pub

Clarendon Irish pub with a divey feel. Live music and more of a late night crowd. Fish and chips was a good portion size. It had a nice crunch. Fries were average. Staff is very friendly and helpful. Good place to grab a beer.

Slow but friendly service, however I cannot deny the size of the fish and chips that I was served. Old-time club feel and good amount of TVs for watching sports.

Been here twice. Both times the server/bartender was friendly, and the beer was top notch at a reasonable price.My first visit here was on Election Night way back in 2016. My friend invited me to an Election Night party at a nearby bar. Bunch of Trumpers there including my friend. I didn't like either of the candidates. Ended up checking out the Libertarian Election Night party at O'Sullivans. Although it wasn't much of a party, the service was great and was my beer along with a couple of good conversation.My 2nd visit here was in June 2023 for a comedy night they do every Thursday night. The server was friendly and prompt with my beer. The atmosphere was comfortable and had some good conversations with others at this comedy Meetup including a couple of the comedians.

This is THE best bar in Arlington post college. I would say once you hit like 24 you're a bit to old but still fun sometimes lol. Also, the dad guys power hour on Fridays is my favorite thing ever

Great place to go to for late night drinks. It's in Clarendon so it's close to the metro and any other options for bar hopping if you're planning on that stuff. Service is quick, and the place is what you expect of a pub. All boxes checked

Met some friends for a post work dinner. Was happy to see we made it right before hh ended. They offered a few $7 food specials which we took advantage of by getting: beef sliders, buffalo chicken dip and fish tacos. Everything was very tasty and really filling. Staff was nice and it was a great seating arrangement outside.

As a die hard Steelers fan, I love a place where I can watch a game and sit in agony for three hours while the Steelers woefully underperform. And O'Sullivan's is the perfect place to do it!This restaurant makes a real effort to make yinzers feel at home. The food specials are good, the wait staff is awesome, and the ambiance is so much fun. I liked the Primanti sandwich (although nothing compares to the original iykyk) and the pretzels rocked too. Hope to catch a win next time but I probably won't lol go Steelers

We really loved the staff and great ambience! My only problem was that our beer was flat. We had two different types and both extremely flat. Total bummer because we really liked the place. Fish and wings were both decent. Will try again and hopeful next time beer will be better.

Irish Pub with a very solid selection of food and drinksFood is comprised of a collection of both Irish and American classicsHave a mixed drink that combines Guinness and one other beer of your choice, but have a bunch of more appetizing mixed drinks as well including a scores espresso martini The fries here are very good, but I got a burger and it was very underwhelming. It was way overcooked and the tomato that came on it was a little old/soggyAll tables are high-tops, and it's pretty loud, so plan accordinglyHappy hour from 4-7Have trivia weekly, and periodically have comedy shows

Really fun atmosphere, clean, and the staff are fantastic! We stopped here on a bar crawl for a friends birthday and had a great time. We didn't have any food so I can't review that feature, but the bar atmosphere was great!
