There are two pizza huts in Chester, one in the town center and one in the greyhound park. The one in the center is nice but small so you might be waiting for a table at peek hours and the one in the greyhound park is big so you usually get a seat, you just need a car to get there.
They serve all types of pizzas along with a kida menu with kids colouring books to keep them entertained. They both have very friendly service and are both clean and nice inside. They have buffets on like all pizza huts at lunch times starting at around 12 (it can change from place to place.)
If you are looking for a nice pizza that you don't want to wait for ever for then visit one of the two pizza huts in Chester, both are great.
