Do any restaurants use horse meat in their hamburgers today?

I really don’t know, and can’t say with 100% certainty. In Europe, many restaurants use horse meat in their products. In other parts of the world I think it’s sometimes used too. I’m not sure about the US. But this isn’t a simple question, there are also a lot of different types of “horse meat” being used, and they’re not the same as “beef”.
