Party venue for 150 people for dinner/dancing

I'm on the hunt for a good party venue for 150 people for dinner/dancing in winter - ideally something quite laid back like a big pub or warehouse space (instead of a hotel).

I've been looking at Tanner Warehouse (formerly Delfina), but it's looking like it would be too expensive.

Any suggestions welcome.

Thank you.

You could see if Matt at The Grange can help ?

We've hired the Union Jack (Union Street) for parties a few times. Bit rough around the edges, but good value if you don't want anything posh.
