Britexpat, yes these types of drinks are available here, I have seen them. To be fair this dry ice (liquid nitrogen) is normally in a big glass with a smaller glass at the top with the actual drink in it so you would have to be pretty stupid to drink the dry ice itself.

Should the bar be held accountable? Well that depends on what actually happened. If the drink was made incorrectly and the girl accidentally drank the liquid nitrogen then they should be. If she decided herself she would drink some of it then no.
