I'll be flying into Chicago next month, and will be arriving HUNGRY. I want to stop for definitive Chicago BBQ to fortify myself for a 2 hour drive that I must then undertake. I kind of have my heart set on Lem's after studying this board, but I want to know - is there anywhere else I should be considering? (Especially if it's closer to O'Hare than Lem's and/or it's a sit-down place - the distance and takeout-only at Lem's might be frowned upon by the folks I'm traveling with.) But, ultimately, I wanna go to the BEST place. Advise me, O Chicago Chowhounds! Thanks in advance!
