Real talk, so far, the only pizza I've ever had that I thought was disgusting and would never, ever have again under any circumstances was pizza I had (against my better judgement) from a Korean place that had it on the menu. My friend wanted pizza and the pizza served 3, and he wasn't going to eat there if he didn't get what he wanted, so fine. It was basically a wide, shallow bread bowl with tomato soup inside. There were floating rubbery bits in the soup that might have been half-thawed cheese shreds of some description, along with some spicy things (some sort of ghost pepper?), unidentifiable green rubbery things, and the weirdest selection of spices I've ever had on pizza. No oregano. It was horrifying garbage, and I would have been happy as a clam having any of the actual Korean specialty dishes, but some people do not want to stray from the eight or nine things they are comfortable eating out, and I generally do not initiate drama.
I essentially guilted my friend into eating at least a third of that disgusting thing.
