In one of Oslo's really old buildings from the relocation and renaming of the town in the 1600's. Great place, pricey, but with some good food and that irish fix when you need it.
I don't dig Irish pubs, but the Dubliner is good. Food is better than you would expect - burgers and chicken dishes are good. Onion rings are tasty but 100 nok - a bit rich for pub food
