There are Ice Bars all over the world now, but Stockholm is home to the world's first permanent ice bar! Everything inside is made of ice... the cups you drink out of, the walls, the chairs, tables, bar, etc.
We went inside during the day to avoid having to wait in line - and loved it. It was a neat experience to wear the big jackets and gloves. We ran into a few other couples from America and it was neat to talk to them.
Ice bar is a little pricey (about $20 to get in, but that includes a drink), but we thought it was worth it because it's the only one we've ever been into. Supposedly, they bring ice in from the Arctic Circle each year to freshen it up. It was cold in there - approx -5 degrees Celsius.
