I saw your post on CH. You got some good info there, though I must say that I have had only very good experiences at Kang Nam, no wood or glass in anything. Also, I always get dol sot bibimbop, and I think Kang Nam's is best. Kang Nam has the added benefit of being in one of America's most interesting culinary strip malls in the middle of one of its most interesting streets. The mall, just north on Kedzie from Lawrence is shared with one of our best Korean grocers, Clark Market -- great panchan to go, Korean liquor, seafood (live geoducks, eg), a good Arab meat market, one of the best Palestinian sweets shops, an Albanian byrek/pizza parlor, and a bank with a cash machine. And a parking lot.
But for novices looking for a good time, I might suggest Garden Buffet -- pick what you like, and eat as much as you want for one relatively low price. Pretty darn good and varied selection of meats, including pork, tripe, and mackerel in addition to your beef, nice stews, and the odd Chinese-Korean dish here and there. Panchan selection is not as high quality or as varied as some of the more traditional places, but you're going for the meat fest, right? Charcoal on the tables. Also, kitschy but somewhat interesting touches such as the pond/stream with lots of turtles and koi.
Not a BBQ place, but one of my favorites is the soju-drenched bizzarely decorated, dark and cozy Korean bar, Hourglass. Very good Korean fried chicken, all you really need to know about the limited menu.
PS, this is a City of Neighborhoods. No good Korean really near the Loop because (unlike LA, eg) luck would have it that the Korean neighborhood isn't near downtown.
