I've gone to the Glendale location several times over the past 2-3 years. I've also been to their Mesa location, but not in 5 years.
I go to watch WWE pay-per-view. At least 5 times a year. I haven't tried it any other time. There's always a good crowd for wrestling events. We have fun.
O'Sullivans is large and has plenty of seats. Lots of TVs of various sizes. Bar is well-stocked. I love Black & Tans (Guinness and Bass). They don't sell Bass, so I settle for Smithwick's, a BlackSmith.
Good food selection. I typically don't experiment with food, I order what I know I'll like. Their meatloaf and shepherd's pie is great. Ribs are o.k. Nacho platter is loaded.
Only problem that I've had, and this has happened on 3 different occasions, is waitress service. First time, during a period when there wasn't a lot of customers around me, I waited 20 minutes to be served. And that was after I notified the manager. He gave me a free drink. Second time, it took 10 minutes. A few weeks ago it happened again. It was very busy and I waited about 8 minutes. Plus waitress brought me the wrong sized drink.
I'll continue to go to R.T. O'Sullivans and report the status of their wait staff.
