Grins was another quasi-Northgate establishment further up College Main in Bryan, 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. By 1984 (may have been as early as 1982), 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). Still later it became Brazos Landing Seafood Grill & Bar (seafood, salads, and burgers--the ad mentioned swordfish, hamburgers, grilled shrimp, blackened chicken, salads, "and more").
Other tenants that I could find and confirm included: Venetian Blind Hospital (or Sturdi-Craft Co.) (1947). Know any others?
Today, the spot is 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.
