Back then, the Pizza was pretty decent, the root beer was excellent, and the sandwiches weren't too bad. While I worked there, they put in the salad bar, stone pizza oven, and pasta bar. I quit after the winter semester in 1986.
Since that time, it has gone downhill. Ownership/management has changed, the pizza recipes have changed, and even the root beer recipe changed. I can't even guess why they changed their recipes, but I would imagine that it might partly be for cost reduction. Or maybe new management thought their new recipes were better/easier/whatever.
I have only been there a handful of times since, and only because I was with a group of others who planned it. It's really sad, I think, because it was an icon, and now it just isn't good.
One last connection for me--this is totally true. Originally it was called Heaps of Pizza, or something like that, after the Heaps that owned it (then later Heaps' Brick Oven, now just Brick Oven). Ken Heaps, one of the original owners was my dad's friend, and was a witness in the St. George temple for my parents wedding.
