The first time I ate at Famous Dave's was umpteen years ago in Minneapolis. The memory of that meal lingers...great ribs and wonderful cornbread.
We went to Chicago this past weekend. First night there ate at Isaac Hayes (Famous Daves). Bottom line first: These wet ribs were among the very best I'd ever had. Absolutely fabulous.
Smoozed with the manager, and between our two visits there, got the lowdown. They smoke in both CS and Southern Pride. I knew our ribs were smoked in CS because there was no smokering.
They are seasoned before smoking with salt and fresh ground pepper, smoked for about 3.5 hours @ 225, removed from the CS, basted with Famous Daves Rich & Sassy Sauce, put on a very hot grill for five minutes and served. Simplicity in a nutshell.
They were tender, juicy, smokey, had a very slight crispiness on the edges, and had that toothsomeness that we love. The sauce on them was not carmelized, nor burnt.
Rib orders are served with cornbread, corn on the cob and two sides. The cornbread was as good as I'd remembered it. Jan isn't in love with cornbread, but liked their's a lot.
Both visits I had Wilbur Beans and fries. The beans were excellent. Not as sweet, thick, nor smokey as I'd have preferred...yet still excellent, with bits of pork and beef mixed in. The fries were cut with a scalloping device and were quite nice.
Their bread pudding is to die for...or from...depending upon how much you stuffed yourself with before dessert. We were stuffed, yet couln't stop eating the bread pudding until it was all gone.
Each of us has different taste buds. If you don't like wet ribs, you're most likely not going to like Famous Dave's, either. You can order Famous Dave's ribs dry, if you prefer.
Frankly, I was shocked that a commercially available sauce (which to us tastes a bit better than Sweet Baby Ray's) could turn smoked ribs into something so special.
All in all a most pleasureable experience.

IMHO Sweet Baby Ray's isn't a bad base at the right price ....We'll see specials on it for $0.49 a bottle and that is cheaper than ketchup. 
If you cut it by a third with vinegar and add your appropriate blend of heat,it makes a decent glaze.....If you are looking to add sweet to the beans on the bottom rack of the CS,it will add sweet!
