Is there specific info that you are after filthiestfis?
Belfast has been going through a huge transformation over the last number of years.. In my opinion, it now has a great range of hotels, bars, clubs, restaurants, shops etc I would be suprised if you didn't find the majority of people in Belfast (and Ireland in general) pretty friendly and helpful. There are many truely beautiful places to visit (Mournes, Antrim Coast etc) and many of the big shows, musicians and concerts etc now have Belfast dates on their tours.
