Ask HN: (UK) Any election night start-up parties ?

There's quite a few election night parties going on in London. It'd be good if we could get a start-up party, or at least see if we can get a lot of startup peeps together at one of the bigger parties.

The NEF party at The Hub would have been ideal, but sadly they're full already.

But would anyone else be up for this and have any suggestions for where to go ?
