Las Vegas - Chicago-Style Italian Beef Sandwich or Philly Cheesesteak Sandwich on Strip?
Neither one are on the strip, but Pops has a good philly cheesesteak and Chicago Hot Dogs has a good italian beef. Both are off the strip (Pops is on decatur and CHD is on N Rancho). If there is a Capriotti's, they have a fair cheesesteak--they are all over Vegas
There is no where on the Strip that I know of to get a Chicago-style Italian Beef. I am from Chicago and live in Vegas. I know all the places in Vegas to go for Chicago style food and I don't think there is any on the Strip but there are places off the Strip if you really want it.
Philly Steak on the other hand I have no idea if it is available on the Strip but there is a very authentic Philly Steak place here in Vegas.
