Shalom, My 19-year daughter Eden (who is not Jewish but whose grandfather was and used to go to the Old-New Synagogue in the late 1930s) will be in Prague between May 3 and June 12 this year. I am wondering if as a non-Jew she is allowed to attend a Shabbat service at the synagogue. Also, are there dress requirements she should be aware of such as not wearing long pants or having to wear a hat? Thank you.
