Nadine Schellenberger, of Zum Gueldenen Stern, a 16th century inn in Ladenburg, failed to recognise the royal couple.
She said King Carl XVI Gustaf and Queen Silvia popped in to her restaurant while she was hosting a wedding reception. "I didn't recognise them. I mean without crowns and sceptres," she said.
"Whether you're a street sweeper or queen – we just didn't have a table or enough manpower in the kitchen at that time and our hands were tied."
However, Mrs Schellenberger and her husband Michael plan to send a letter to the King and Queen to apologise.
"We want to tell them that we are sorry we didn't recognise them immediately and that we weren't able to serve them but that we would be delighted to welcome them another time," she said.
Press reports said the royal couple and their entourage managed to get a pizza on the market square.
