I have been to pizza hut in many occasions and have also had take away from then numerous times. Their pizzas always seem to be cooked fresh and they are generous with the amount of ingredients they put on. They have an excellent selection of sides, drinks, pastas and desserts too. They are also very helpful at accommodating your needs for example I love their vegetarian pizza but hate fresh tomatoes on pizza so always ask for it without and they always accommodate this. Their pizza's tend to taste fresh and I would recommend them. You can also have a choice of base from thin crust, deep pan, stuffed crust to cheesy bites.
Their prices are also fairly reasonable and they do have good deals on both in the restaurants and for take away. At the moment they are still doing kids eat free in their restaurants with a paying adult. This can be ideal when you have children. They also do 50% and lots of buy one get one free on their take away menu.
Their restaurants tend to be fairly clean but I do think this can depend on where you go. I have always found the staff friendly and helpful and would recommend it as a good place to eat out on a budget or if you don't want to spend much.
