In reply to Oogachooga:
So, anything with ropes Beacon has better walls. Indy has some decent routes but they're short and not many of them. Indy is by far the better bouldering gym and place to be in general. If you really want a day on ropes and can cope with the scowls then it's worth the £3.
But I'm very much an Indy guy and it's my second home so take that into consideration when I dish out my opinion, I'm also a boulderer, so don't really care much about the routes...
Also worth noting they're having a refurb right now so are closed Monday and Tuesday I believe.
