I liked this episode less than I did the first one. Even though they blew through St. Louis and featured the best thing, IMHO, in St. Louis out of many: Ted Drewe's frozen custard. AB was certainly brave in trying to learn how to mix the concrete, and yes I am one of those who will wax nostalgic about Ted Drewes until I die.
The segment on Colonel Sanders is pretty interesting but the tidbits on Tea rooms and fried brain sandwiches were a little lame, I thought. The pork steak BBQ was pretty interesting, I didn't realize it reached that far south, oh well, live and learn. I am too big of an Alton Brown fan to give this one up, but I was not impressed.
The best parts of the show have been the background info that they did on each of the segments. The segments themselves weren't all that.
