Grins was another quasi-Northgate establishment further up College Main in Bryan, 4410 College Main to be precise, and reportedly hosted some great live entertainment acts in its day. I've heard that the only "drinking" opportunities they had was Coors Light, so I'm guessing the food wasn't too fantastic either. The above advertisement came from November 1979. From 1983-1985, it was Dr. G's, unrelated to the later Mr. G's, Dr. G's ("The Remedy", it advertised) offered live music, soups, salads, burgers, sandwiches, and Mexican food (likely beer, too, though the ad didn't mention that). Morganstern's was in the spot from 1986 to 1988. Still later (1989) it became Brazos Landing Seafood Grill & Bar (seafood, salads, and burgers--the ad mentioned swordfish, hamburgers, grilled shrimp, blackened chicken, salads, "and more"). That same year it was listed simultaneously as Texas Star Tavern. (Hmm.)
Since 1992, however, it has been Junction Five-o-Five, which despite its name, isn't a bar or other entertainment establishment. A picture of the current building was taken in June 2014 by me, and current Street View.
Other tenants that I could find and confirm included: Venetian Blind Hospital (or Sturdi-Craft Co.) (1947). I haven't found anything else yet or when it became a bar (or when it stopped becoming residential, as it presumably originally was).
