I went to the one out in the suburbs of chicago. Think it was called Oakbrook, or Buffalo Grove, or something like that. I also thought it was more cool to watch the kettles go, than the food was good. The one on the show was not the one I went to. It was more urban, and alot nicer, newer on the inside.
As for Weber cubes to start those? They must have had about 40 to get flames shooting out of the top by that much. It looked like to me that the bottom coals would probably be the size of dimes by the time the top ones were done with all that fire shooting up the middle. Also, they looked to be sitting in little circular depressions on the metal counters- -like they were designed to be there.
And lastly, looked like the main ones were ranch kettles, but there were some smaller ones for cooking the fruit and other small stuff.
