Is the meat here halal?

I heard back directly from the restaurant manager via email, they said that all of their chicken is halal

No, it's not

I would chat with the folks at the restaurant via phone or email. It is my understanding that some but not all of their meat is halal.

Make sure they understand the meaning of halal. Some items do specify whether or not the meat is halal.

Are they providing Kosher meat instead of halal meat?

Thank you for the response John toward Yamaan. I was going to say, call the restaurant for sure tp ask.

I do not think it is.
