Pub church is when people gather in a pub or bar to talk about God and have fun. It's like going to church, but instead of sitting in pews and listening to a preacher, you get to sit at a table with your friends and have a drink while you talk about God. Pub church is meant to be a fun and relaxed way for people to think and talk about their faith. So, it's like a regular church, but in a pub and with a slightly different experience.
