The pastor tacos are some of the best in Chicago. Also, dude behind the counter is super friendly and patient even when your drunk friends are taking forever to order.
Authentic, yet delicious "no-frills" tacos. Tried the carne asadadinner combo and was very pleased. Cashier was very friendly. Note: limited seating and cash only.
One of those hole in the wall places where you would still eat if you had all the money in the world. Service is amazing. Tacos are somehow even better.
