70s/80s kid here. At our "old house" (we moved in 1980 when I was in 3rd grade), there was a local pizza place that we would order from. It was an occasional treat -- definitely not weekly, and probably not monthly, but it also wasn't "birthdays only" or anything like that. Like you said, the restaurant was very bar-like so we never ate there, but we'd get take out. I liked to go with my dad to pick it up because you could see into the kitchen and they had the pizzas in a big rotary oven.
After we moved (to a rural area) there was no place close to get pizza, so if we had it at all, we'd make it at home. But homemade pizza wasn't anybody's favorite, so we didn't have it often. My dad occasionally had to travel for work. When he was gone, mom would sometimes take us into town to go to Pizza Hut. Apparently we hurt dad's feelings because we'd get a little *too* excited to find out he would be leaving town. Oops! ;-)
