It's a very very studenty place tbh, what was you looking to do? The two main nightclubs I know of, Chill and Club Chemistry are very very studentsville, I went there when I was 24 the last time I remember and I felt like mother hen compared to most of the people there! But I guess if your on a hen night and a bit merry it would be a laugh!
The old brewery tavern is quite a laugh tho, always enjoyed it there!
Only a few miles from canterbury is whitstable also which has the brewery bar and it's quite a quirky little village with a zizis, prezzo and lots of little cute restraunts!
Have arranged my friend's hen party for this weekend. Staying about 3 miles out of Canterbury but would like to head into town on Saturday to do a bit of moseying/ pub lunch. Any recommendations? Keeping it pretty low key.
