My damn search turned up a Sydney bar first even though I specifically put "Adelaide" in the search query. Thanks, Google. And I didn't realise until I had spent some time verifying specifically that it will show the Stanley Cup final and then wanted to check where exactly it was.

Anyway, I've done a bit of a search and don't love the results. Nothing looked promising to me. This might be your best hope since the pub is open early enough, but the sports bar part only opens at 11. Could be worth reaching out and enquiring? If you've got a bunch of mates who want to join you maybe they'd put it on for yous in the regular bar?

I don't personally like promoting casinos but If it's anywhere it's probably Skycity
