The Cambridge beer festival have a great time.
I have often thought this festival would be a good venue for a ICB meet up as it is so close to Stanstead airport, it would be easy for all to get to from Cork, Dublin. Belfast, [i:1e30vmjv]and of course Knock.[/i:1e30vmjv]
I think they run a winter festival Jan/Feb. you might make some enquiries?
