Tbh Bainy I would go to Enter whatever they do - it's a really sociable atmosphere on that night so going on your own is very easy.
If your mates want to go to Cream they can still go - unless their tastes are very eclectic, if Calvin Harris is their bag then they may well not really 'get' Enter musically, and nothing worse than being at a night you walk into and think "Wow this is great" and end up :
1) Listening to moaning about the fact mates wanted to go somewhere else and they hope you realize what a compromise they're making ... before, during and/or after
2) Having your vibe dampened by people who aren't enjoying themselves

; and
3) Probably having your arm twisted to leave early
