Norwich is alot better than Gt. Yarmouth.
Princes of Wales road is the main place for all the clubs in Norwich, come out the train station and go straightover the bridge and your on Price of Wales road.
There is Riverside just round the corner from the trainstation too, instead of going over the bridge turn left and you will see it, lots of good bars at Riverside.
Most people go to Riverside to a bar first then onto Price of Wales to a club.
