Where should I setup a bank account in Reykjavik?

"To setup a bank account in Reykjavik, you should visit one of the local banks and branches, such as Arion Bank, Landsbankinn, and Íslandsbanki. All of these banks offer comprehensive banking services, including setting up new bank accounts. Before setting up a bank account, it’s wise to bring your passport or other identification document, proof of address in Reykjavik, and some other documents as required by the bank. Additionally, it may be helpful to contact the bank beforehand to see what documents and information you need to provide in order to set up an account," remarked another expat who made the move to Reykjavik, Iceland.
