This used to be the Jameson Bonded warehouse, back in the day - so it's worth a look for that alone. It's cheaper to park in than most other car parks in the city centre (i think) and there's a reason for that. It's smelly, damp and toight - which is probably why they have guys to do the parking for you. At the weekends though you can do the parking yourself and maybe even take one of the big old bays around the edges which have plenty of space (they stack cars in them during the week)...it's alot bigger than you'd think from looking at the entrance, taking up most of the block - worth a try...
