Looking for a Chicago Style Italian Beef

I'm from Illinois and one of my favorite things that I missed from there is Italian beef. I looked around the internet and I saw there was some food truck called Chicago me up that used to sell Chicago style food including an Italian beef. I haven't been able to find any more information about it, I think it might not exist anymore. Does anyone know where I can find a Chicago style Italian beef near downtown Miami / Brickell area? I don't even care if it's overpriced, I just really want it.
