My wife is in love with all things Chicago so I decided to try Windy City Beefs-N-Dogs and was pleasantly suprised. Windy City Beefs-N-Dogs has its strong points and its weak points. One thing I do like about this restaraunt is that they use very high quality ingredients. I had a beef and sausage sandwich and the beef was fresh and juicy and the sausage was huge (no dinky small sausage around here). I also liked this relish like substance they put on their sandwich, which is a combination of carrots, peppers, and onions. The Au Jus was delicious.
One thing I would say though is this is not a place to go if you are trying to monitor your cholestrol or even lose a few pounds. Everything is greasy and fattening, but this is not necessarily a bad thing if it is done right (and in this case it is). The only complaint I had about my sandwich is that it might use some more seasoning as it was slightly bland. It is possible though this is a more stylistic attribute of the Chicago style food so I can't complain.
All in All Great place.
