Do they have Kosher or Halal meat?

Yes they have Kosher meat. Anything in "green" packing is kosher certified according to an employee at the store.

You can get halal lamb leg at costco, check if its in stock

I haven't really been looking for that but I haven't seen it there

I don't think so..

Check the web site

Well it might not heart to go to the store to see. Or just call the store it's self.

I'm not sure as I don't eat meat
