okay so I am assuming that this is not limited to zabeeha and kosher..but I will not kosher ones
my current favs are Nathans, and BallPark Angus.
hebrew national are pretty good as well.
Nathans you can get kosher
Vienna beef has good ones but you have to make sure they dont have pork casing, some of their products do some dont varies by product type. its a local chicago based brand.
