Big John has no characteristics. He personally doesn't like it.
Saizeriya is an Italian pizza, which is different from Pizza Hut and Papa John's nothingness pizza. Tomato sauce and cheese are the main ingredients, but there are few other ingredients on it, but it has a unique flavor. Among them, tuna mayonnaise pizza is quite delicious, and all the food is very cheap, about half that of Pizza Hut.
Anyway, I personally like Saizeriya or Pizza Hut.
But if you want to eat pizza, Pizza Hut is the best. If you want to eat cheap snacks or steak, lamb chops, hamburgers and Saizeriya are the best.
