Pizza 4P's Hoang Thanh Tower is a wood-fired pizza restaurant on the first and second floors of Hoang Thanh Tower in Hanoi's Hai Ba Trung district. It serves crab pasta, porcini sauce pizza, and squid ink risotto, and an open kitchen shows the cooking process. The restrooms are kept clean and plates are cleared from the dining room quickly. Weekend lunchtimes draw a crowd and the room gets hot.
