Yesterday, I discovered that the Subway on George Bush Drive (Southgate, at Montclair) closed for good, so this is hot off the presses as far as this blog is concerned. I don't know the backstory of 330 George Bush (originally 330 Jersey), but I try my best here. From what I can find, in 1956, it was the home of Pruitt's Fabrics (moved down a few spaces fairly early on, although dropped "Fabrics" in recent years). By the early 1960s it was Fugate-Davidson Printers.
An oral history transcript mentions that Fugate shut down that location and moved "back to the house" in 1970 before selling out in 1973, this house presumably being at or near where Fish Richard's was located.
In 1988, it became Beef 'N Brew (which did not seem to have been related to "Beef & Brew", where The Tap is today, nearly a decade earlier). By late 1991, it was Subway, and Subway it would be for a number of years afterward. The (many) Subway stores around town are operated by Centex Subway, and from working at the stores at one time, most of them do marginal business. The COVID-19 problems (especially related to students on campus and around town) wiped out a lot of business, with the Southgate store being hit particularly hard, and after a temporary closure, was made permanent.
I can't find most of the tenant history, with only the notes where Beef N Brew's application suggesting it was part of Rother's (next door) at one time (and indeed, the property lines for the business include the former Rother's next door and what is now Good Bull BBQ).
For the purposes of blog organization, I'm going to assume the building dates back to the 1940s but I don't have any hard proof of that.
UPDATE 05-24-2021: Subway opened in fall 1991, shortly after Beef 'N Brew (which was not related to the former business at The Tap) officially closed earlier that year. This has been appended in the main article.
UPDATE 02-10-2024: In 2022 it became "FNL Nutrition" (sold juices, smoothies, etc.) which also occupied the Good Bull BBQ space next door. It ended up closing by fall 2023.
