There are 31 states in the country of Mexico.
Not every state has its own cuisine, but certainly there are 10 to 15 areas making its own indigenous food.
By far my favorite area, making the very best food this country has to offer is Oaxacan cuisine from (of course) the state of Oaxaca (Duh) located in Southern Mexico.
Corn and chili peppers are a main staple for this food, but it's their "Mole" sauces that always get my attention!
Last night I went to Kie-Gol-Lanee (the one in Logan Square) that served very original Oaxcan food that didn't disappoint. The owners and the people working here are "Spot-on"!
We (my wife and I) started our dinner with guacamole and chips then moved on to Enchiladas De Pollo and Camarones a la Diabla; everything brought to our table was fantastic.
When we moved to Chicago three years ago from Los Angeles, I thought I would miss all of my East L.A. Mexican restaurants. To my surprise, Chicago not only met my L.A. mexican food expectations, but actually surpassed it.
Places like Kie-Gol-Lanee make it a a joy to have here!
