I'm going to be the bearer of bad news and tell people going Cov Uni that you will get bored in Coventry, simply for the fact the city doesn't have anything going for it. The nightlife here is an absolute embarassment. Considering the city's size you'd expect better but it's a joke.
Lava/Ignite aka Ikon/Diva is for the cheese and R&B lovers you can get in any city, Colosseum for the Indie lot, Dog and Trumpet for the freaks and outcasts, Dogma for those with some cash (they have Breakbeat and House in there so it's not that bad), Careys for House music lovers/posers and Release for Hip Hop/R&B/Dancehall/etc. You have more places like Jailhouse (live music), Jumping Jacks (pulling your mate's mum), etc but really ain't worth mentioning. At least with Cov there's enough roads to get out, and you can get to Warwick Uni, Leamington, Birmingham, Leicester, etc really easily and quickly but otherwise nightlife is just standard chain bars like Wetherspoons, Yates's, etc and rubbish clubs (mentioned above).
Can't really say much more about Coventry. The city centre looks like a concrete Blade Runner set in Kosovo sometimes and the local radio stations are still crap 20 years later. Memorial Park is nice I guess and the taxis are cheap(er) then other big cities... oh yeah and the Coventry Cathedral is quality, has to be visited by absolutely everybody. Some of the city centre is being done up and looks proper slick like the bit where the Transport Museum is, plus it's getting some new hardcore restaurant where the old fire station is. More bars are getting opened up as well last time I checked. No complaints from all my mates either who stayed home about Cov Uni itself so you'll definitely enjoy it. Just can't recommend the city or it's nightlife too much, but this is one man's opinion. You'll probably go and it be the complete opposite of what I've rambled about. Explore the place is all I can really say. Sorry to piss on everyone's bonfire
