I'm guessing it is somewhere in Italy by the language o n the signs - and that it is something to do with food by the chef's hat of the guy in the doorway.
Rome?
pizza?
Cant comment o n the cost - or the rest of the excursion - but we went to the lunch and singing with Scenic.
We had choice of a S of M walking tour first or a general Salzburg one, which we did.
I'm not into the Sound of Music at all and didnt really think I would enjoy it (was included excursion so no point not going though) - actually was great fun, it wasnt all about the Sound Of Music and one didnt need to be a S of M fan to enjoy it.
oh ok.
de-gendered terms like wait staff, service staff ,admin staff, nursing staff etc are common place here
You dont need a new word, existing words can convey occupations etc without gender.
