I've had a few opportunities to try OTPH. Besides a regular "any day" visit, I've experienced New Years Eve, bingo night, and community yoga. Three very different experiences, and all very good. New Years Eve was a lively experience with lots of fun and laughter, full but not overcrowded. Bingo night was a little more family friendly, very casual, but a fun and relaxing way to enjoy a beer. Community yoga on Saturday mornings isn't always at OTPH, and the bar isn't open during this time, but it is a beautiful space for a quiet hour of yoga.
I highly recommend checking this place out, especially when they have live music. They get some very talented bands and performers that you'll want to hear again.
