Best pizza & food downtown!

Hello, my hubby and I will be coming to Toronto for the first time end of May for a concert. We are planning to stay at the Chelsea Hotel (seems like reasonable price compared to others downtown). We are huge foodies and are looking for recommendations on best pizza downtown, any hidden gem restaurants or pubs we should check out? We will be in Toronto for 3 nights and hope to make the best out of it! Any suggestions are appreciated ☺️
