Pubs/places to watch The Open? ⛳️

My parents are travelling from Australia to come watch The Open (Golf) in July. They are retired and play golf almost every day, absolutely crazy for it, so its quite a big deal that they're coming here for the event. They have tickets for the Saturday, and want to watch the play from a pub somewhere on the Sunday. I'd really like to make the weekend special for them, but I live in London and have no idea where to take them - Liverpool is foreign to me. 

TLDR: Any recommendations for a place I can book/ go to watch The Open while in Liverpool?

Any help would be greatly appreciated 🙏
