There is also a Jims in East Moline on 10th St, just east of where 92 splits into one ways. I have not been to Jims since the old man died, but I found the ribs to be too dry and expensive. When I want ribs I smoke my own on my Green Egg, but -7 today us a bit chilly to cook outside. I really don't have an alternative to suggest for outstanding ribs. I too recommend Whitey's.
Don't go to the Jim's in E Moline, just Rock Island. Ribs the same as back in the 70's, 80's etc. Got 10 slabs in Aug.
