Jim mentioned the Burnet Barbecue in Union, NJ a while back. It is a small place that grills chicken and ribs over wood charcoal.
I finally got a chance to try it today, and it is (no surprise) very good. The owner sprays the chicken and ribs with some hot sauce while they are grilling and that doesn't hurt.
The address is 1363 Burnet Ave, very near the Garden State Parkway and 78, and the owner told me that he has another larger place at 1275 Stuyvesant Avenue in Union, as well.
