It casts the same spell as pizza. You'd have a hard time finding someone who doesn't really enjoy it. It even works on people who don't generally like salads.
That's an incredibly American take IMO. Pizza is loved worldwide... Caesar salad?! Where are the famous Caesar salad global chains? I don't think it's much of a thing in Europe, at least.
Maybe, but it simply isn't a thing here. I think the only time I've seen it is in McDonald's. I literally had to google it because I only heard the name but didn't know what it was.
