Just to put in my 2 cents for Taco El Tio #4, I have been there four times and on the whole I have found it extremely delicious. So far I have tried tacos of various types, including the steak, tripe, brisket, al pastor, "steamed head" ie cabeza, chicken and tongue, as well as nachos, quesadilla, guacaomole and menudo.
The tripe taco has been particularly good, and trying it "crispy" was nice as well. On 2 of the 4 trips the steak taco was excellent, easily on par with Don Alfredo in my opinion, although on the other days it was rather dry. I would skip the chicken taco and the quesadilla, and the tacos al pastor and menudo were fine but I wouldn't get them again, but all the other tacos were very tasty, especially if you add one of the two salsas (a green avocado based one that is pretty mild and a slightly spicier red one).
Overall I am very happy to have this rather authentic Mexican place in Oak Park, so that I finally can eat some good Mexican very close to home. I have found going on Taco Tuesday might be the best time, since they tend to have a heavy take out going and everything seems to be fresh on that night. That being said, the deal for Taco Tuesday is 5 taco al pastors for $12.99, and unfortunately that is one of my least favorite tacos they make, so we just go and get the regular menu items.
Just to juxtapose this new place to the new Mexican on Madison (Taco '76), I have gone once there for lunch and found it much more "Americanized". The food was fine, but I wouldn't go back anytime soon.
