One drink is called “Iced In Tea Fada,”
That doesn't sound very subtle. I wonder if this guy really did come to the cafe by coincidence or if it was an act of protest. Either way, the proprietor doesn't seem to have a good legal defense...
Edit: The place has an Arabic logo but otherwise it looks like a completely normal Bay Area hipster cafe. (Although I suppose that Bay Area hipster cafes aren't particularly welcoming to people prominently displaying a Star of David.) "Iced In Tea Fada" really is on the menu.
