San Francisco has some of the best restaurants anywhere – and one of the most unique. Mozzeria, ranked among the top pizza places in the city, is also one of the first to be entirely owned and operated by people who are deaf.

Melody and Russell Stein opened the place in 2011, and it's been a foodie favorite from the start.

Their 900-degree wood-fired oven is the best they could find, and so is every ingredient, from sauce to sausage, to cheese, some of which comes from Italy. "We also make it in-house," said Melody, signing.

"And if that doesn't make you hungry, I don't know what will," added Russell.
