Best I've had in the country: Dirty burger - Kuma Corner in Chicago Clean burger - Sidetrack in Ypsilanti Sidetrack also has the best sweet potato fries, perfect cut, crispness and seasoning. But if you are a dirty fries person, then this place I live next to in St. Louis now, the Kitchen Sink, has some awesome ones dipped in melted marshmallows and maple syrup. Houston can compete with any city. Petrol Station and Lankford Grocery are among the best I've ever had. Last year when I was living in the Heights, I loved biking over to the Hubcap on 19th and getting a double with sweet potato fries. Man, those were the days.
