A trip into Norwich is the best option,I would not go near GY with a barge pole,its honestly a dump,plenty to do and see within a couple of mins walk from Norwich station.
Pubs galore and eating houses galore,however Prince of wales rd can be a bit busy on a fri/sat night but plenty of good fun for all.
have a great weekend if you want any places to go in Norwich PM me and I will give you my number you can then ring me for a chat about where to go etc
I am local and have lived in Norwich all my life so I could be called an expert,altough others would call me different
