Moving here from the Chicago area 8 years ago, I have struggled to find a good hot dog that represents the best of Chicago style cuisine.  Well, in my opinion, Windy City's hot dogs are as good (or better) than any that Chicagoland offers.  Their fries are also very tasty and complement well any of their sandwiches.  Although I am sure that most folks might find the Italian Beef to be excellent, it is just a little spicy (too much black pepper) for my palette.  The Italian Sausage is also excellent, and the best you can find anywhere!  I gave the deep dish pizza a shot and the quality was excellent, however, the sauce was a little sweet for my taste buds...(I am a big fan of Lou Malnati's in Chicago).  My preference for pizza in Las Vegas is Rosati's thin crust version.  You can't go wrong at Windy City, and I strongly recommend you make a trip over here soon....you won't regret it!  I plan to stop in anytime I'm in the area.
