I am looking for undiscovered Mexican restaurant gems in the Chicagoland area. I went to a place called Nuevo Leon last weekend and was amazed at the quality, quantity and low, low price of the food. What further amazed me with that this establishment has been around for over thirty years, and has received 4 forks from the Chicago Tribune as well as being Zagat rated and I never heard of it. The way I see it if I missed one there has to be more out there that are worth a visit. Any input anybody has is greatly appreciated.
