In reply to Rokmunky:
To be honest, I've never really enjoyed the climbing at Chedder. I hear it starts to get good in the 7s but in the 5s and 6s, you're mostly looking at polished roadside. The stuff in Dorset is much better at those grades and you have a lot more to choose from.
The other thing about Cheddar is the AWFUL boy racers. The steep sides of the gorge make their winkys tingle when they rev their engines, and the multiple little carpark bays make it an ideal meet for them. It really ruins my time there.
Depending on where you are based, you might want to have a look at some south wales sandstone. It's not much harder to get to than Cheddar from the m4, and there are a number of great crags with 5s and 6s and a different variety of climbing than the lime. Navigation Quarry, Tirpentwys, Sirhowy, The Gap, Bargoed, to name a few good ones.
