There are two good ale pubs at the station - The Head of Steam & the King's Head. The former does cooked food too, not sure about the KH. Away fans are welcome at the Gas Club on the way to the ground. Lots of ale houses in Huddersfield
There will be plenty of people with Block 6 tickets who will want to stand so if you can't get a Block 6 ticket you should be able to swap. I doubt you will even be asked to move
