I love Steakumm. They're fine with me.
Anyway, there's two places I get decent cheesesteaks. I'm not sure which one I'd rank better, because I don't live near the one anymore, but I do get it on occasion.
Mr. Assante Pizza in Green Brook, NJ - Don't just get a cheesesteak. Ask them for my special "cheesesteak, onions, on top of garlic bread". It's amazing. Get peppers if you want too.
Do the same thing at Varriale's Pizza in Whiting/Manchester Township, NJ.
People have actually heard me order it and have ordered it as well. I told them to put it on the menu yet they did not.
