Be careful where you park. I have heard there is a lot of restricted parking area's close to the IceBar and a lot of people did not relize this and came out to find their cars were towed.
Brilliant Ill keep an eye out on grupon! Was just thinking it might be a nice surprise and something different for mum. I have been to the icebar in Stockholm and it was a really good experience so by the sounds of it its along the same lines as in they are all very alike.
