The exception to that (besides the Blinn one) was the first Taco Bell in the area was 3901 South Texas Avenue, Taco Bell #1261. This operated from September 1976 to 1996 and was colloquially known as Archie's Taco Bell (even in advertising, though not on the building).3 Archie's Taco Bell had a unique (and annoying) quirk—for whatever reason (allegedly due to traffic flow), the drive-through window was on the passenger side. The 1996 closure date lines up with the opening of the Taco Bell at 3501 East 29th Street (which has the drive-through window built correctly, but like Northgate's it wasn't built as a Taco Bell), so it might have moved at that point4. In 2003, the abandoned building was expanded and heavily modified to be Frittella Italian Cafe, operated by the sons of the owner of the original Pino's in Houston. Frittella closed at the end of March 2022, but reopened in June 2023. (I'm not sure of the reason.)
1. In the 1970s, which this entry covers, most Taco Bell food was prepared fresh, not overly processed like it is today. This 1970s commercial may seem like propaganda, but in those days they really did do stuff like make beans from dry.
2. Updated as of this writing. It doesn't change much but confirms the dates and adds a bit on the Texaco it replaced.
3. Archambault built a few more local Taco Bell stores before he retired, the Harvey Road Taco Bell was "Archie's Taco Bell" as well.
4. Indeed, in 1998, even after Archambault had divested his share in Taco Bell, 3501 E. 29th Street is listed as "store number one" for local purposes.
