This was a traditional Irish spot with a long bar and loud setting. There was also an upstairs where private events and other engagements seemed to occur. The service was appreciated, and everything came out in a timely manner. The chicken quesadilla and pretzel sticks were ordered. The quesadilla came with sour cream, salsa, and guacamole. The quesadilla was good. There was plenty of seasoning present on the chicken as well as cheese. The salsa and guacamole were a nice touch too. The pretzel sticks came with their Guinness cheese sauce. There were three sticks to an order. They had plenty of salt present and came out hot. They were very soft and went well the cheese sauce. The cheese sauce was on the thinner side with plenty of flavor present. Will I go back? Yeah, sure.

This is a solid pub in the area. It's just off Atlantic Ave, near the Barclays center. The inside is very spacious and it seems great for groups. When we walked in, they weren't playing the premier league game, but they happily put it on when we asked. The service was very attentive and consistently checked up on us, even when the bar started getting pretty busy. We ordered the wings and they were so delicious. They were so juicy and covered in sauce. I usually don't like wings and wouldn't order them, but these changed my mind. For drinks, I got a cider and it was as expected. My partner got an ale, which apparently tasted stale and as if they didn't clean the pipes. He tried a few other beers and said the same. I couldn't really taste the difference, but something to keep in mind if you're very familiar with beer. I'd keep this place in mind if you need a sports bar in the area!

Came here after a Nets game and enjoyed a tasty fish and chips. The fish was battered great and was especially crispy. The loaded fries were ok the cheese was not 100% melted but other than that the fries were crispy and had the right amount of salt. The service was great and we were seated promptly

Just a good ol' standard Irish bar/sports bar. Lots of TVs, the usual booze selection, average prices. If this is what you're going for, McMahon's will give it to you.

Fun pub very close to Barclays Arena. We fell upon this as a pregame spot before our event at the arena. Nice size pub with big bar, dining area and second floor seating. Drink menu was good and the my have Guinness which is all I really want from a pub. Food menu includes Irish nachos, calamari, bangers and mash. All the standard pub foods. Service was fast and friendly. Our server Samantha was very good. It's the city so private parking nonexistent. Street parking or parking garages are your option. Stop in before your concert or game for a drink.

I'm not even a bar food kind of girl, but I would return here simply because of the excellent customer service I received here tonight. The bartender had a full bar yet continuously came over to check on us in our booth. Our drinks were exactly how we requested it.. and their kitchen was the only kitchen open late within the 2 blocks we walked searching. It was very clean and well kept. Can't wait to return here.

We stopped into McMahons after having dinner at Patsy's Pizzeria. We came in for a drink at the bar & the live music. Gerry (bartender) was gracious & attentive. Checked on us numerous times. The live music was an added bonus to a great nite before heading back to catch LIRR.

Wanted to watch the Knicks and the Nets this past Wednesday and this was the perfect place for that. With big tv screens, live band, and so many beer options two thumbs up. Very spacious long bar, back area for dining and an upstairs, very good for big groups, company outings, and a hot fun day. I had the Irish egg rolls, chipotle bbq wings, and a Cesar salad, there was a little wait for my food but the bartender compensated by providing an extra set of drinks on the house very well appreciated. The Irish spring rolls were definitely a hit, and the chipotle bbq sauce on the wings was something like no other for my drink I had the octoberfest and a cranberry and vodka well made. I'll definitely be back :)
