For some reason McKibbin's is one of the go-to's of my friends so I gave it a go about a year ago. I understood why very quickly! The atmosphere is nice, surprisingly not noisy even though the bar is big (probably due to the very good placements of heavy duty wooden walls that diminish the sound), good quality furniture and appropriate spacial management for seating, very welcoming bar and a friendly staff.
The food is also decent. It's at McKibbin's where I fell in love with sweet potato fries! There is also a stage for the occasional bands. I've heard two play which were mediocre at best. Surprisingly a lot of security but I understood the need after I've seen a bad drunk threatening to get the Russian mafia to shoot the pub up after getting thrown out of a bar.
I've never tried The Rim Reaper Challenge as I already passed 20 minutes under a sink with tears rolling down my cheeks after trying Cage Aux Sports' 9-1-1 hot wings and didn't wish to permanently damage my taste buds but it seems quite fun if you think you're up to it!
+1 for deep fried pickles! (I liked them and I usually hate pickles 0.o!)
The one thing that killed it for me is the price of the beer. 19.95$ FOR A PITCHER OF MOOSEHEAD?!? WHAT THE F****! McKibbin's has without a doubt the most expensive pitchers of piss-tier beer I've ever seen.
