We have a few from over the years. Here are a couple of our probably very favorites:
Shakey's Pizza, Grand Prairie, TX. We would always stop at this Shakey's Pizza as kids, when Mom and Dad would drive in from Biloxi Mississippi, then after that, from Abilene TX (Dad was in the Air Force). I remember us younger kids (my brothers and one sister) used to get the biggest kick out of watching them make the pizzas through a big long glass viewing window. Priceless memories.
Yum Yum Tree, Oahu HI. We used to take the kids there once or twice a month (it was a different time back in the 90's). My two older boys still remember the place, and the food. There is a commercial on YouTube from the 90's that show a combo plate of steak, BBQ chicken, and ribs, with veggies and a salad, for $10.95.
It's Greek To Me, San Antonio, TX. This little place was run by a Greek couple, as most good Greek places are. We used to eat here quite a bit, and got to where the owners (and a couple of the servers that stuck around) knew us. What made it really special is after my wife and I moved to the Houston area, my youngest son still went there a lot. When he got sick (Ulcerative Colitis), these guys helped him a lot and treated him like a son. When they finally retired and closed shop, we went back there to see them one last time before they closed. Very good people, and very good food.
