We've covered Pizza Hut before (both the classic University Drive East location and the short-lived Northgate proper location (see the older two posts) so here's a third location (and between the various carry-out locations, there's still room to grow). I submitted it on Used to Be a Pizza Hut (expecting it to be in the queue for months, but no, it's on there already). The Navasota store was featured over ten years ago on the site, and it's now a funeral home, too...possibly the first "Funeral Hut" covered. It operated from November 1966 (first Pizza Hut in the area) to sometime in 2002 (closed without replacement) and briefly served as Lone Star Pawn for a few years afterward before becoming Treviño-Smith Funeral Home in 2007.
What I can't figure out is what it looked like originally. 1966 is a bit young for the iconic red roof and Pizza Hut claims that it wasn't implemented until 1969, but the Wikipedia article indicates the first restaurant done was in 1963. Maybe it was indeed the first of its type in Texas.
