UBS do a good package for couples and if you are new customers you have reduced fees. You get a maestro card, a personal current account, a savings account and can open up other types as well. It is also possible for you to have a joint account with your partner, (again with maestro card, and savings account). you can choose to have your correspondence in German, French, Italian or English.
Go to UBS and speak to them, they were very helpful.
I do know that Credit Suisse do something similiar as well.
Talking with the bank is actually a relaxing experience in Switzerland!
