Do you want to exchange the currency or withdraw Franks from ATM using your EUR card?
If you withdraw from the Post Finance ATM (I found one in Luzern train station) , you get the best rate. Withdrawing CHF from ATM gives better rate than currency exchange.
If you want to exchange currency, you can also try at the train ticket office.
Using credit card or debit card is much better than currency for your transactions.
