Pizza Hut Restaurants Piccadilly is a pizza restaurant on Regent Street in London's Piccadilly Circus that sells pizza and desserts. On weekday lunchtimes it runs an unlimited buffet of pizza, salad and nachos, and Margherita and ham pizza can also be ordered. The pizza comes out freshly baked and desserts are sold alongside it, and the toppings are on the sparse side. The cutlery and plates are dirty and the store's cleanliness is poor.
