Die besten Restaurants mit Turkisches restaurant Essen in Marktoberdorf

We wanted to eat with a voucher book on Friday evening, mind you, the restaurant was 1/4 full, and received an answer that the voucher book is not valid today. Sorry, but what's that supposed to mean? Then don't even join in!! Exclusion criteria are Sundays and public holidays. Is Friday a holiday? Then they left again, apparently Marmaris doesn't need to make sales! Disappointing.
