"Hello Pizza is a charming family-owned restaurant that offers delicious and creative pizzas, with their specialty being a crust stuffed with Sweet Potato Mousse that can be added to any pizza. I was pleasantly surprised by the unique twist on the stuffed crust, as I found the mousse to be delicious. I tried the potato pizza with the mousse, which was topped with potatoes, corn, onions, cheese, and sauce. While the potatoes were a bit underwhelming, the overall flavor was fantastic. My wife enjoyed the gluten-free veggie pizza with a generous amount of veggies on top. They also offer vegan cheese as an option. Our child loved the heart-shaped mushroom pizza, and the restaurant had a fun and friendly atmosphere with games and a Lego table for kids. Overall, Hello Pizza is a standout spot in the La Cañada Flintridge area and definitely worth a visit."
