My thanks go to Terry Bates for letting me scan pages from his copy of this 1968 guidebook to Houston. There some interesting items in it; we'll start with the restaurants.
I recognize many of them and remember the locations of some I never patronized. I noticed Bud Bigalow's is listed. It was a pretty good steak house.
The printer didn't leave enough gutter space, so some info is obscured by the page fold. Nevertheless, you can read most of it.
