forty two, sounds like a good idea - but what is John Hewitt? A Pub? And almost as important: where?
I'd be interested in transport, as I fly in - if I come...?

I've been to Belfast, but I can't remember very much, certainly not a John Hewitt...
The only "Hewitt" I could locate on my Belfast street map is "Hewitt Parade" (between Strandtown, Bloomfield and Ballyhackamore)
