One word for this place: Authentic.
I'm from Chicago, and I'm sick of going someplace, ordering a "Chicago dog," and having some girl from Thousand Oaks serve me something that is anything but Chicago-style. Not here.
This place has legit Chicago everything. Real Maxwell St. Polish and Italian beef. The Giardiniera is authentic Chicago-style, awesome--no nasty vinegar, just high quality olive oil. If you live too far to get lunch here regularly, I'd stop in and buy Giardiniera to go, it's just that good.
If you're from Chicago you will appreciate a true dipped beef sandwich, an absolute mess of deliciousness. Truly the taste of home. There's nothing like watching the Bulls win or the Cubs lose while enjoying an authentic beef sandwich.
For non-Chicagoans, I can't promise that you'll love it. But I can assure you that this is by far the most authentic Chicago hotdog place in Las Vegas. Can't beat it for a $10 lunch.
