This is a great spot if you want to have a quiet lunch. The food is delicious. It is more expensive than a lot of places but I think this reflects its quality. Thank you

I have been a wedding guest may times at Belfast, City Hall, and have found that since it's refurbishment in the late 1990's it has become a beautiful place for second marriages and those who don't want the trappings and cost of the traditional wedding.
At the moment you would enter from the rear of Belfast City Hall and although you don't get the initial grandeur of the big staircase its all there for the photo opportunities after the ceremony. The service itself is always lovey and is just the right amount of time. I do believe you can have different services but you would have to check that out.
As for the location it can't get much better, slap bang in the centre and all but one of the weddings I attended have had the reception at Belfast Castle so there has only been a short commute.
Overall I would recommend Belfast City Hall as you get all the decor of a traditional church in a superb location without the extra cost.
