Favazza's on the Hill is a family-owned Italian restaurant in St. Louis's historic Hill neighborhood, founded in 1978 by Vito Favazza, his wife Ellen, and their son Tony.

The menu draws on classic Italian recipes passed down through generations, featuring house-made pastas and wood-fired specialties. For private events, Favazza's offers a range of dedicated spaces across the restaurant, from an outdoor pavilion and plaza accommodating up to 150 guests to private dining rooms and a lower-level wine room suited for more intimate gatherings.
