For the seventh year, the Portland Harbor Hotel is holding its three-day Ice Bar event, which started Thursday night and was expected to attract as many as 400 patrons during its premiere.

Sponsored by Rokk Vodka of Sweden and by Shipyard Brewing Co. in Portland, the event is open to ticket holders from 5 to 9 each night.

Hundreds more are expected to visit the sculpted ice bars in the next couple of nights, sampling complimentary hors d’oeuvres and enjoying live entertainment.
